 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)
 Q10. CBSE Class 8 Maths Factorisation Mcq The factors of 3m2 + 9m + 6 are: A. (m + 1) (m + 2) B. 3(m + 1) (m + 2) C. 6(m + 1) (m + 2) D. 9(m + 1) (m + 2)
Ans: 3(m + 1) (m + 2)
Hint:
3m2 + 9m + 6 = 3(m2 + 3m + 2)
= 3 [m2 + m + 2m + 2]
= 3 [m(m + 1)+ 2( m + 1)]
= 3 [(m + 1) (m + 2)]
