CBSE Class 8 - Mathematics - Factorisation - NCERT Exercise (14.2)

Factorisation

NCERT Exercise 14.2

Q1: Factorise the following expressions.

(i) a² + 8a + 16

(ii) p² − 10p + 25

(iii) 25m² + 30m + 9

(iv) 49y² + 84yz + 36z²

(v) 4x² − 8x + 4

(vi) 121b² − 88bc + 16c²

(vii) (l + m)² − 4lm (Hint: Expand (l + m)² first)

(viii) a⁴ + 2a²b² + b⁴


Answer:

(i) a² + 8a + 16 = (a)² + 2 ☓ a ☓ 4 + (4)²

= (a + 4)² [(x + y)² = x² + 2xy + y²]


(ii) p² − 10p + 25 = (p)² − 2 ☓ p ☓ 5 + (5)²

= (p − 5)² [(a − b)² = a² − 2ab + b²]


(iii) 25m² + 30m + 9 = (5m)² + 2 ☓ 5m ☓ 3 + (3)²

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

(iv) 49y² + 84yz + 36z² = (7y)² + 2 ☓ (7y) ☓ (6z) + (6z)²

= (7y + 6z)² [(a + b)² = a² + 2ab + b²]

(v) 4x² − 8x + 4 = (2x)² − 2 (2x) (2) + (2)²

= (2x − 2)² [(a − b)² = a² − 2ab + b²]

= [(2) (x − 1)]² = 4(x − 1)²

(vi) 121b² − 88bc + 16c² = (11b)² − 2 (11b) (4c) + (4c)²

= (11b − 4c)² [(a − b)² = a² − 2ab + b²]

(vii) (l + m)² − 4lm = l² + 2lm + m² − 4lm

= l² − 2lm + m²

= (l − m)² [(a − b)² = a² − 2ab + b²]

(viii) a⁴ + 2a²b² + b⁴ = (a²)² + 2 (a²) (b²) + (b²)²

= (a² + b²)² [(a + b)² = a² + 2ab + b²]

Factorisation

NCERT Exercise 14.1 Solutions

Q1: Find the common factors of the terms

(i)   12x, 36

(ii)  2y, 22xy

(iii)  14pq, 28p²q²

(iv) 2x, 3x², 4

(v) 6abc, 24ab², 12a²b

(vi) 16x³, −4x², 32x

(vii) 10pq, 20qr, 30rp

(viii) 3x²y³, 10x³y², 6x²y²z

Answer:

(i) 12x = 2 ☓ 2 ☓ 3 ☓ x

36 = 2 ☓ 2 ☓ 3 ☓ 3

The common factors are 2, 2, 3.

And, 2 ☓ 2 ☓ 3 = 12

(ii) 2y = 2 ☓ y

22xy = 2 ☓ 11 ☓ x ☓ y

The common factors are 2, y.

And, 2 ☓ y = 2y

(iii) 14pq = 2 ☓ 7 ☓ p ☓ q

28p²q² = 2 ☓ 2 ☓ 7 ☓ p ☓ p ☓ q ☓ q

The common factors are 2, 7, p, q.

And, 2 ☓ 7 ☓ p ☓ q = 14pq

(iv) 2x = 2 ☓ x

3x² = 3 ☓ x ☓ x

4 = 2 ☓ 2

The common factor is 1.
