Solution:

(i) Given y + 1/y

y + 1/y is not a polynomial because in this given equation the second term becomes 1 Ã— y-1Â where -1 is not a whole number. So, the given algebraic expression is not a polynomial.

(ii) Given 2-5âˆšx

2-5âˆšx is not a polynomial because again the power of x is 1/2 which is not a whole number.

(iii) Given x2Â + 7x + 9

The given algebraic expression is a polynomial in one variable because all the powers of x are whole numbers.

(iv) Given 2m-2Â + 7m â€“ 5

This expression is not polynomial because the power of the first term is -2 which is not a whole number.

(v) Given 10

The number 10 is a polynomial because 10 can be represented as follows: 10 Ã— x0Â which is equal to 10. So, it is a polynomial.

Solution:

i. In the standard form of any polynomial it is necessary for the power of the variable to go in descending order for each term.

So, the standard form of this polynomial is as follows:

m3Â + 5m + 3

ii. In the standard form of any polynomial it is necessary for the power of the variable to go in descending order for each term that is first term should consist of variable with highest power, second term should contain the variable with second highest power and so on.

So, the standard form of this polynomial is as follows:

âˆ´Â The given polynomial in coefficient form is:

(1, 0, 0, -2)

ii. In the coefficient form of the polynomial, the coefficient of each term of the variable present or absent is written inside the simple brackets. So, the coefficient form is as follows:

â‡’Â 5y = 5.y + 0

Therefore, the given polynomial in coefficient form is:

(5, 0)

iii. In the coefficient form of the polynomial, the coefficient of each term of the variable present or absent is written inside the simple brackets. So, the coefficient form is as follows

2m4Â â€“ 3m2Â + 7 = 2.m4Â + 0.m3Â â€“ 3.m2Â + 0.m + 7

Therefore, the given polynomial in coefficient form is:

(2, 0, -3, 0, 7)

iv. In the coefficient form of the polynomial, the coefficient of each term of the variable present or absent is written inside the simple brackets.

Now in this case all the powers of the variable are zero and only the constant is present.

So, the coefficient form is as follows:

ii. (5, 0, 0, 0, -1)
iii. (-2, 2, -2, 2)

Writing in the index form, the polynomial is:

â‡’Â 1.x3Â + 2x2Â + 0.x + 3

â‡’Â x3Â + 2x2Â + 3

âˆ´Â Index form of polynomial is x3Â + 2x2Â + 3

ii. The given representation is the coefficient form of the polynomial. So, the first coefficient denotes the highest power of the variable and the power of last term is always zero.

= 5.x4Â +0.x3Â + 0.x2Â + 0.x â€“ 1

= 5x4Â â€“ 1

Therefore, the index form of the polynomial is = 5x4Â â€“ 1

iii. The given representation is the coefficient form of the polynomial. So, the first coefficient denotes the highest power of the variable and the power of last term is always zero.

= -2.x3Â + 2.x2Â â€“ 2.x + 2

= -2x3Â + 2x2Â â€“ 2x + 2

Therefore, the index form of the polynomial is = -2x3Â + 2x2Â â€“ 2x + 2

iii. The tens and units place of a two-digit number is m and n respectively. Write the polynomial which represents the two-digit number.

Solution:

i. Given,

Total number of trees in the village = a

Increase in the number of trees by = b

Now we have to find number of trees after x years

Number of trees in x years = (a + b) x

ii. Given,

Number of students in each row = y

Number of rows of Students = x

So total number of students = x Ã— y

vii. When x = â€“ 1, what is the value of the polynomial 2x3Â + 2x ?
(A) 4
(B) 2
(C) -2
(D) -4

Solution:

(A) 4

Explanation:

Put x = -1 throughout the polynomial

= 2 Ã— (-1)3 + (2 Ã— -1)

= -2 -2

= -4

viii. If x â€“ 1 is a factor of the polynomial 3x2Â + mx, then find the value of m.
(A) 2
(B) -2
(C) -3
(D) 3

Solution:

(C) -3

Explanation:

Put x = -1 throughout the polynomial

= 2 Ã— (-1)3 + (2 Ã— -1)

= -2 -2

= -4

ix. Multiply (x2Â â€“ 3) (2x â€“ 7x3Â + 4) and write the degree of the product.
(A) 5
(B) 3
(C) 2
(D) 0

Solution:

(A) 5

Explanation:

The multiplication is as follows:

= (x2Â -3) Ã— (2x â€“ 7x3Â + 4)

= x2.2x â€“ 7x3.x2Â + 4x2Â -3.2x + 3.7x3Â -3.4

= 2.x2+1Â â€“ 7x3+2Â + 4x2Â -6x + 21x3-12

= 2x3Â â€“ 7x5Â + 4x2Â â€“ 6x + 21x3Â â€“ 12

Therefore, the degree of the product is 5.

x. Which is the following is a linear polynomial?
(A) x + 5
(B)Â x2Â + 5
(C) x3Â + 5
(D) x4Â + 5

Solution:

(A)Â x + 5

Explanation:

A polynomial is said to be linear if the highest power of the variable is one. So, among the options x + 5 only has highest power as one.

2. Write the degree of the polynomial for each of the following.
i. 5 + 3x4
ii. 7
iii. ax7Â + bx9Â (a, b are constants)

Solution:

i. 5 + 3x4

Here, the highest power of x is 4.

âˆ´Degree of the polynomial = 4

ii. 7 = 7xÂ°

âˆ´ Degree of the polynomial = 0

iii. ax7Â + bx9

Here, the highest power of x is 9.

âˆ´Degree of the polynomial = 9

3. Write the following polynomials in standard form. [1 Mark each] i. 4x2Â + 7x4Â â€“ x3Â â€“ x + 9
ii. p + 2p3Â + 10p2Â + 5p4Â â€“ 8

Solution:

i. 7x4Â â€“ x3Â + 4x2Â â€“ x + 9

ii. 5p4Â + 2p3Â + 10p2Â + p â€“ 8

4. Write the following polynomial in coefficient form.
i. x4Â + 16
ii. m5Â + 2m2Â + 3m+15

Solution:

i. x4Â + 16

Index form = x4Â + 0x3Â + 0x2Â + 0x + 16

âˆ´ Coefficient form of the polynomial = (1,0,0,0,16)

ii. m5Â + 2m2Â + 3m + 15

Index form = m5Â + 0m4Â + 0m3Â + 2m2Â + 3m + 15

âˆ´ Coefficient form of the polynomial = (1, 0, 0, 2, 3, 15)
