## Factorisation Worksheet Class 8 Maths

Factorisation is a important mathematical concept, especially in algebra, essential for simplifying expressions and solving equations. In CBSE Class 8 Maths, the Factorisation chapter teaches students to express algebraic expressions as products of their factors. By breaking down complex expressions into simpler factors, students can solve problems efficiently and understand algebraic manipulation better. This chapter covers several techniques for factorising algebraic expressions. These techniques include common factorisation, factorisation by grouping, and special factorisation formulas such as perfect squares and cubes. Mastery of factorisation not only aids in solving mathematical problems but also forms the basis for advanced topics in algebra and calculus.

### Class 8 Maths Factorisation Worksheet Questions with Answers

Q1. Factorise the following expressions.
(a) 54m3n + 81m4n2
(b) 15x2y3z + 25x3y2z + 35x2y2z2
Solution:
(a) 54m3n + 81m4n2
= 2 × 3 × 3 × 3 × m × m × m × n + 3 × 3 × 3 × 3 × m × m × m × m × n × n
= 3 × 3 × 3 × m × m × m × n × (2 + 3 mn)
= 27m3n (2 + 3mn)

(b) 15x2y3z + 25 x3y2z + 35x2y2z2 = 5x2y2z ( 3y + 5x + 7)

Q2. Factorise the following polynomials.
(a) 6p(p – 3) + 1 (p – 3)
(b) 14(3y – 5z)3 + 7(3y – 5z)2
Solution:
(a) 6p(p – 3) + 1 (p – 3) = (p – 3) (6p + 1)
(b) 14(3y – 5z)3 + 7(3y – 5z)2
= 7(3y – 5z)2 [2(3y – 5z) +1] = 7(3y – 5z)2 (6y – 10z + 1)

Q3. Factorise the following:
(a) p2q – pr2 – pq + r2
(b) x2 + yz + xy + xz
Solution:
(a) p2q – pr2 – pq + r2
= (p2q – pq) + (-pr2 + r2)
= pq(p – 1) – r2(p – 1)
= (p – 1) (pq – r2)

(b) x2 + yz + xy + xz
= x2 + xy +xz + yz
= x(x + y) + z(x + y)
= (x + y) (x + z)

Q4. Factorise the following polynomials.
(a) xy(z2 + 1) + z(x2 + y2)
(b) 2axy2 + 10x + 3ay2 + 15
Solution:
(a) xy(z2 + 1) + z(x2 + y2)
= xyz2 + xy + 2x2 + zy2
= (xyz2 + zx2) + (xy + zy2)
= zx(yz + x) + y(x + yz)
= zx(x + yz) + y(x + yz)
= (x + yz) (zx + y)

(b) 2axy2 + 10x + 3ay2 + 15
= (2axy2 + 3ay2) + (10x + 15)
= ay2(2x + 3) +5(2x + 3)
= (2x + 3) (ay2 + 5)

Q5. Factorise the following expressions.
(а) x2 + 4x + 8y + 4xy + 4y2
(b) 4p2 + 2q2 + p2q2 + 8
Solution:
(a) x2 + 4x + 8y + 4xy + 4y2
= (x2 + 4xy + 4y2) + (4x + 8y)
= (x + 2y)2 + 4(x + 2y)
= (x + 2y)(x + 2y + 4)

(b) 4p2 + 2q2 + p2q2 + 8
= (4p2 + 8) + (p2q2 + 2q2)
= 4(p2 + 2) + q2(p2 + 2)
= (p2 + 2)(4 + q2)

Q6. Factorise:
(a) a2 + 14a + 48
(b) m2 – 10m – 56
Solution:
(a) a2 + 14a + 48
= a2 + 6a + 8a + 48
[6 + 8 = 14 ; 6 × 8 = 48] = a(a + 6) + 8(a + 6)
= (a + 6) (a + 8)

(b) m2 – 10m – 56
= m2 – 14m + 4m – 56
[14 – 4 = 10; 4 × 4 = 56] = m(m – 14) + 6(m – 14)
= (m – 14) (m + 6)

Q7. Factorise the following polynomials.
(a) 16x4 – 81
(b) (a – b)2 + 4ab
Solution:
(a) 16x4 – 81
= (4x2)2 – (9)2
= (4x2 + 9)(4x2 – 9)
= (4x2 + 9)[(2x)2 – (3)2] = (4x2 + 9)(2x + 3) (2x – 3)

(b) (a – b)2 + 4ab
= a2 – 2ab + b2 + 4ab
= a2 + 2ab + b2
= (a + b)2
