EXERCISE 14.1 PAGE NO: 14.5

Solve the following quadratic equations by factorisation method only:

1. x2 + 1 = 0

Solution:

Given: x2 + 1 = 0

We know, i2 = –1 ⇒ 1 = –i2

By substituting 1 = –i2 in the above equation, we get

x2 – i2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x + i) (x – i) = 0

x + i = 0 or x – i = 0

x = –i or x = i

∴ The roots of the given equation are i, -i

2. 9x2 + 4 = 0

Solution:

Given: 9x2 + 4 = 0

9x2 + 4 × 1 = 0

We know, i2 = –1 ⇒ 1 = –i2

By substituting 1 = –i2 in the above equation, we get

So,

9x2 + 4(–i2) = 0

9x2 – 4i2 = 0

(3x)2 – (2i)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(3x + 2i) (3x – 2i) = 0

3x + 2i = 0 or 3x – 2i = 0

3x = –2i or 3x = 2i

x = -2i/3 or x = 2i/3

∴ The roots of the given equation are 2i/3, -2i/3

3. x2 + 2x + 5 = 0

Solution:

Given: x2 + 2x + 5 = 0

x2 + 2x + 1 + 4 = 0

x2 + 2(x) (1) + 12 + 4 = 0

(x + 1)2 + 4 = 0 [since, (a + b)2 = a2 + 2ab + b2]

(x + 1)2 + 4 × 1 = 0

We know, i2 = –1 ⇒ 1 = –i2

By substituting 1 = –i2 in the above equation, we get

(x + 1)2 + 4(–i2) = 0

(x + 1)2 – 4i2 = 0

(x + 1)2 – (2i)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x + 1 + 2i)(x + 1 – 2i) = 0

x + 1 + 2i = 0 or x + 1 – 2i = 0

x = –1 – 2i or x = –1 + 2i

∴ The roots of the given equation are -1+2i, -1-2i

(2x – 3)2 – (4i)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(2x – 3 + 4i) (2x – 3 – 4i) = 0

2x – 3 + 4i = 0 or 2x – 3 – 4i = 0

2x = 3 – 4i or 2x = 3 + 4i

x = 3/2 – 2i or x = 3/2 + 2i

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x – 2 + 3i) (x – 2 – 3i) = 0

(x – 2 + 3i) = 0 or (x – 2 – 3i) = 0

x = 2 – 3i or x = 2 + 3i

(x + 1)2 + (–i2) = 0

(x + 1)2 – i2 = 0

(x + 1)2 – (i)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x + 1 + i) (x + 1 – i) = 0

Solution:

Given: 5x2 – 6x + 2 = 0

We shall apply the discriminant rule.

Where, x = (-b ±√(b2 – 4ac))/2a

Here, a = 5, b = -6, c = 2

So,

x = (-(-6) ±√(-62 – 4 (5)(2)))/ 2(5)

= (6 ± √(36-40))/10

= (6 ± √(-4))/10

= (6 ± √4(-1))/10

We have i2 = –1

By substituting –1 = i2 in the above equation, we get

x = (6 ± √4i2)/10

= (6 ± 2i)/10

= 2(3±i)/10

= (3±i)/5

x = 3/5 ± i/5

∴ The roots of the given equation are 3/5 ± i/5

So,

x = (-9 ±√(92 – 4 (21)(1)))/ 2(21)

= (-9 ± √(81-84))/42

= (-9 ± √(-3))/42

= (-9 ± √3(-1))/42

We have i2 = –1

By substituting –1 = i2 in the above equation, we get

x = (-9 ± √3i2)/42

= (-9 ± √(3i)2/42

= (-9 ± √3i)/42

= -9/42 ± √3i/42

= -3/14 ± √3i/42

∴ The roots of the given equation are -3/14 ± √3i/42

(x – 1/2)2 + ¾ × 1 = 0

We know, i2 = –1 ⇒ 1 = –i2

By substituting 1 = –i2 in the above equation, we get

(x – ½)2 + ¾ (-1)2 = 0

(x – ½)2 + ¾ (-i)2 = 0

(x – ½)2 – (3i/2)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x – ½ + 3i/2) (x – ½ – 3i/2) = 0

(x – ½ + 3i/2) = 0 or (x – ½ – 3i/2) = 0

(x + 1/2)2 + ¾ × 1 = 0

We know, i2 = –1 ⇒ 1 = –i2

By substituting 1 = –i2 in the above equation, we get

(x + ½)2 + ¾ (-1)2 = 0

(x + ½)2 + ¾ i2 = 0

(x + ½)2 – (3i/2)2 = 0

[By using the formula, a2 – b2 = (a + b) (a – b)]

(x + ½ + 3i/2) (x + ½ – 3i/2) = 0

(x + ½ + 3i/2) = 0 or (x + ½ – 3i/2) = 0

So,

x = (-(-8) ±√(-82 – 4 (17)(1)))/ 2(17)

= (8 ± √(64-68))/34

= (8 ± √(-4))/34

= (8 ± √4(-1))/34

We have i2 = –1

By substituting –1 = i2 in the above equation, we get

x = (8 ± √(2i)2)/34

= (8 ± 2i)/34

= 2(4±i)/34

= (4±i)/17

x = 4/17 ± i/17

∴ The roots of the given equation are 4/17 ± i/17

ix2 + xi2 + 12i = 0

i(x2 + ix + 12) = 0

x2 + ix + 12 = 0

x2 + ix – 12(–1) = 0

x2 + ix – 12i2 = 0 [Since, i2 = –1]

x2 – 3ix + 4ix – 12i2 = 0

x(x – 3i) + 4i(x – 3i) = 0

(x – 3i) (x + 4i) = 0

x – 3i = 0 or x + 4i = 0

x = 3i or –4i

∴ The roots of the given equation are -4i, 3i

(x) x2 – (32 – 2i)x – 2i = 0

Given: x2 – (32 – 2i)x – 2i = 0

We shall apply the discriminant rule.

Where, x = (-b ±√(b2 – 4ac))/2a

Here, a = 1, b = -(32 – 2i), c = –2i

So,

(xi) x2 – (2 + i)x + 2i = 0

Given: x2 – (2 + i)x + 2i = 0

x2 – (2x + ix) + 2i = 0

x22x – ix + 2i = 0

x(x – 2) – i(x – 2) = 0

(x – 2) (x – i) = 0

(x – 2) = 0 or (x – i) = 0

x = 2 or x = i

∴ The roots of the given equation are i, 2

(xii) 2x2 – (3 + 7i)x + (9i – 3) = 0

Given: 2x2 – (3 + 7i)x + (9i – 3) = 0

We shall apply the discriminant rule.

Where, x = (-b ±√(b2 – 4ac))/2a

Here, a = 2, b = -(3 + 7i), c = (9i – 3)

So,

We can write 16 + 30i = 25 – 9 + 30i

16 + 30i = 25 + 9(–1) + 30i

= 25 + 9i2 + 30i [∵ i2 = –1]

= 52 + (3i)2 + 2(5)(3i)

= (5 + 3i)2 [∵ (a + b)2 = a2 + b2 + 2ab]

By using the result 16 + 30i = (5 + 3i)2, we get
