a. 1

b. 2

c. 3

d. -1

Answer: b

Explanation: The coefficient of x2 in equation 3x3+2x2-x+1 is the multiple of x2.

3) A binomial of degree 20 in the following is:

a. 20x + 1

b. x/20 + 1

c. x20 +1

d. x2+20

Answer: c

Explanation: A polynomial having two terms and the highest degree 20 is called a binomial of degree 20.

4) The degree of 4x3-12x2+3x+9 is

a. 0

b. 1

c. 2

d. 3

Answer: d

Explanation: The degree is the highest power of a variable in an equation.

5) x2 – x is ________ polynomial.

a. Linear

b. Quadratic

c. Cubic

d. None of the above

Answer: b

Explanation: A polynomial of degree two is known as quadratic polynomial.

6) x – x3 is a ________ polynomial.

8) The value of f(x) = 5x−4x2+3 when x = -1, is:

a. 3

b. -12

c. -6

d. 6

Answer: c

Explanation: When x= -1

f(x)=5x−4x2+3

f(−1)=5(−1) −4(−1)2+3

=−5–4+3

=−6

9) The value of p(t) = 2+t+2t2−t3 when t=0 is

a. 2

b. 1

c. 4

d. 0

Answer: a

Explanation: p(0)=2+0+2(0)2–(0)3=2

10) The zero of the polynomial f(x) = 2x+7 is

a. 2/7

b. -2/7

c. 7/2

d. -7/2

Answer: d

Explanation: f(x)=2x+7

⇒2x+7=0

⇒2x=−7

⇒x=−7/2

∴x = −7/2 is a zero polynomial of the polynomial f(x).
