Q1.	Learn Cbse Class 8 Maths Mcq The factorisation of 12a²b +15ab² gives:
	A. 3ab(4ab + 5)
	B. 3ab(4a + 5(b)
	C. 3a(4a + 5(b)
	D. 3b(4a + 5(b)

Ans: 3ab(4a + 5(b)
Hint:
12a²b+15ab²
12a²b = 3 x 4 x a x a x b
15ab² = 3 x 5 x a x b x b
The common factors are 3ab.
12a²b + 15ab² = 3ab(4a +5b)

Q2.	Mcq Class 8 Maths Chapter 14 The factorisation of 12x + 36 is
	A. 12(x + 3)
	B. 12(3x)
	C. 12(3x + 1)
	D. x(12 + 36x)

Ans: 12(x + 3)
Hint:
12x + 36
12 x + 12 . 3
= 12(x + 3)

Q3.	Mcq for Class 8 Maths Chapter 14 On factorising 14pq + 35pqr, we get:
	A. pq(14 + 35r)
	B. p(14q + 35qr)
	C. q(14p + 35pr)
	D. 7pq(2 + 5r)

Ans: 7pq(2 + 5r)
Hint:
14pq + 35pqr
= 2.7.p.q + 5.7.p.q.r
= 7pq(2 + 5r)

Q4.	Mcq Questions for Class 8 Maths with answers pdf Chapter 14 The factors of 6xy – 4y + 6 – 9x are:
	A. (3x + 2) (2y + 3)
	B. (3x – 2) (2y – 3)
	C. (3x – 2) (2y + 3)
	D. (3x + 2) (2y – 3)

Ans: (3x – 2) (2y – 3)
Hint:
6xy – 4y + 6 – 9x
= 6xy – 4y – 9x + 6
= 2y (3x – 2) – 3 (3x – 2)
= (3x – 2) (2y – 3)

Q5.	Mcq Questions for Class 8 Maths with answers pdf download The factors of x² + xy + 8x + 8y are:
	A. (x +y) (x + 8)
	B. (2x + y) (x + 8)
	C. (x + 2y) (x + 8)
	D. (x + y) (2x + 8)

Ans: (x +y) (x + 8)
Hint:
x² + xy + 8x + 8y
= x(x + y) + 8(x + y)
=(x + y)(x + 8)

Q6.	Ncert Class 8 Maths Mcq Chapter 14 The factors of 4y² – 12y + 9 is:
	A. (2y + 3)²
	B. (2y – 3)²
	C. (2y – 3)(2y + 3)
	D. None of the above

Ans: (2y-3)²
Hint:
4y² – 12y + 9
4y² = (2y)² & 9 = 3² & 12y = 2.3.2y
4y² – 12y + 9 = (2y)² – 2 × 3 × (2y) + (3)²
= (2y – 3)² [By algebraic identities: (a-(b)² = a²+b²-2ab

Q7.	Ncert Class 8 Maths Mcq Questions The factors of 49p² – 36 are:
	A. (7p + 6)²
	B. (7p – 6)²
	C. (7p – 6 ) ( 7p + 6)
	D. None of the above

Ans: (7p – 6 ) ( 7p + 6)
Hint:
49p² – 36 = (7p)² – ( 6 )² = (7p – 6 ) ( 7p + 6)

Q8.	CBSE Class 8 Maths Chapter 14 Mcq The factors of m² – 256 are:
	A. (m + 4)²
	B. (m – 4)²
	C. (m – 4) (m+4)
	D. None of the above

Ans: None of the above
Hint:
m⁴ = (m²)² and 256 = (16)²
m⁴ – 256 = (m²)² – (16)² = (m² – 16) (m² + 16)
m² – 16 = m² – 4² = (m – 4) (m + 4)
m⁴ – 256 = (m – 4) (m + 4) (m² + 16)

Q9.	CBSE Class 8 Maths Chapter 14 Mcq Questions When we factorise x² + 5x + 6, then we get:
	A. (x + 2) (x + 3)
	B. (x – 2) (x – 3)
	C. (x × 2) + (x × 3)
	D. (x × 2) – (x × 3)

Ans: (x + 2) (x + 3)
Hint:
The factors of a form:
(x + (a) (x + (b) = x² + (a + (b) x + ab
x²+ 5x + 6
a + b = 5 and ab = 6
x²+ 5x+6 = (x + 2) (x + 3)
