C. 3a(4a + 5(b) 

D. 3b(4a + 5(b) 
Ans: 3ab(4a + 5(b)
Hint:
12a^{2}b+15ab^{2}
12a^{2}b = 3 x 4 x a x a x b
15ab^{2} = 3 x 5 x a x b x b
The common factors are 3ab.
12a^{2}b + 15ab^{2} = 3ab(4a +5b)

A. (2y + 3)^{2} 

B. (2y – 3)^{2} 

C. (2y – 3)(2y + 3) 

D. None of the above 
Ans: (2y3)^{2}
Hint:
4y^{2 } – 12y + 9
4y^{2} = (2y)^{2} & 9 = 3^{2} & 12y = 2.3.2y
4y^{2 } – 12y + 9 = (2y)^{2} – 2 × 3 × (2y) + (3)^{2}
= (2y – 3)^{2} [By algebraic identities: (a(b)^{2} = a^{2}+b^{2}2ab
Hint:
4y^{2 } – 12y + 9
4y^{2} = (2y)^{2} & 9 = 3^{2} & 12y = 2.3.2y
4y^{2 } – 12y + 9 = (2y)^{2} – 2 × 3 × (2y) + (3)^{2}
= (2y – 3)^{2} [By algebraic identities: (a(b)^{2} = a^{2}+b^{2}2ab
Q7.  Ncert Class 8 Maths Mcq Questions The factors of 49p^{2} – 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:
49p^{2} – 36 = (7p)^{2} – ( 6 )^{2} = (7p – 6 ) ( 7p + 6)
Hint:
49p^{2} – 36 = (7p)^{2} – ( 6 )^{2} = (7p – 6 ) ( 7p + 6)
Q8.  CBSE Class 8 Maths Chapter 14 Mcq The factors of m^{2} – 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:
m^{4} = (m^{2})^{2} and 256 = (16)^{2}
m^{4} – 256 = (m^{2})^{2} – (16)^{2} = (m^{2} – 16) (m^{2} + 16)
m^{2} – 16 = m^{2} – 4^{2} = (m – 4) (m + 4)
m^{4 } – 256 = (m – 4) (m + 4) (m^{2} + 16)
Hint:
m^{4} = (m^{2})^{2} and 256 = (16)^{2}
m^{4} – 256 = (m^{2})^{2} – (16)^{2} = (m^{2} – 16) (m^{2} + 16)
m^{2} – 16 = m^{2} – 4^{2} = (m – 4) (m + 4)
m^{4 } – 256 = (m – 4) (m + 4) (m^{2} + 16)
Q9.  CBSE Class 8 Maths Chapter 14 Mcq Questions When we factorise x^{2} + 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) = x^{2} + (a + (b) x + ab
x^{2 }+ 5x + 6
a + b = 5 and ab = 6
x^{2 }+ 5x+6 = (x + 2) (x + 3)
Hint:
The factors of a form:
(x + (a) (x + (b) = x^{2} + (a + (b) x + ab
x^{2 }+ 5x + 6
a + b = 5 and ab = 6
x^{2 }+ 5x+6 = (x + 2) (x + 3)
Q10.  CBSE Class 8 Maths Factorisation Mcq The factors of 3m^{2} + 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:
3m^{2} + 9m + 6 = 3(m^{2} + 3m + 2)
= 3 [m^{2} + m + 2m + 2]
= 3 [m(m + 1)+ 2( m + 1)]
= 3 [(m + 1) (m + 2)]
Hint:
3m^{2} + 9m + 6 = 3(m^{2} + 3m + 2)
= 3 [m^{2} + m + 2m + 2]
= 3 [m(m + 1)+ 2( m + 1)]
= 3 [(m + 1) (m + 2)]
