## 9th Class Math Chapter 5 Factorization Short Questions Answer

Factorize the following x² + 8x + 16 – 4y²

Solution:

= (x + 4)² – (2y

= (x + 4 + 2y)(x + 4 – 2y)

= (x + 2y + 4)(x – 2y + 4)

Factorize the following 4x² – 16y²

Solution:

= 4(x² – 4y²)

= 4 [(x)² – (2y)²]

= 4(x + 2y)(x – 2y)

Factorize the following 9x² + 27x + 8

Solution:

= 9x² + 24x + 3x + 8

= 3x (3x + 8) + 1 (3x + 8)

= (3x + 8)(3x + 1)

Factorize the following 1 – 64z³

Solution:

= (1)³ – (4z

= (1 – 4z)[(1)² + 1(4z) + (4z)²]

= (1 – 4z)(1 + 4z + 16)

Factorize the following 8x³ – 1/27y³

Solution:

= (2x)³ – (1/3y

= (2x – 1/3y)[(2x) + 2x 1/3y + (1/3y)²]

= (2x – 1/3y)(4x² + 2x /3y + 1/9y²)

Factorize the following 2y² + 5y – 3

Solution:

= 2y² + 5yy – 3

= 2y(y + 3) – 1(y + 3)

= (y + 3)(2y – 1)

Factorize the following x³ + x² – 4x – 4

Solution:

= x²(x + 1) – 4(x + 1)

= (x + 1)(x² – 4)

= (x + 1)(x² – 2²)

= (x + 1)(x + 2)(x – 2)

Factorize the following 25m²n² + 10mn + 1

Solution:

= (5mn)² + 2(5mn)(1)+(1)²

= (5mn + 1)²

Factorize the following 1 – 12pq + 36 p²q²

Solution:

= (1)² – 2(6pq) + (6pq

= (1 – 6pq
