Q1.	CBSE Class 8 Maths Mcq Questions The factorisation 1 + 16x + 64x² is
	A. (1 – 8x)²
	B. (1 + 8x)²
	C. (8 – x)²
	D. (8 + x)²

Ans: (1 + 8x)²
Hint:
1 + 16x + 64x²
= (1)2 + 2(1) (8x) + (8x)² = (1 + 8x)²

Q2.	CBSE Class 8 Maths Factorisation Mcq Questions The factorisation x² + x + \(\frac{1}{4}\) is
	A. (\(\frac{x}{2}\) – 1)²
	B. (\(\frac{x}{2}\) + 1)²
	C. (x + \(\frac{1}{2}\))²
	D. (x – \(\frac{1}{2}\))²

Ans: (x + \(\frac{1}{2}\))²
Hint:
x² + x + \(\frac{1}{4}\) = x² + 2(x)(\(\frac{1}{2}\)) + (\(\frac{1}{2}\))²
= (x + \(\frac{1}{2}\))²

Q3.	Class 8 Maths Mcq Chapter 14 The value of 99² is
	A. (90)² + 2(90)(9) + (9)²
	B. (90)² – 2(90)(9) + (9)²
	C. (90)² + (9)²
	D. none of these.

Ans: (90)² + 2(90)(9) + (9)²
Hint:
99² = (90 + 9)²
= (90)² + 2(90)(9) + (9)²

Q4.	Class 8 Maths Mcq online test The value of 49² is
	A. (50)² – 2(50)(1) + (1)²
	B. (50)² + 2 (50) (1) + (1)²
	C. (50)² – (1)²
	D. (50)² + (1)²

Ans: (50)² – 2(50)(1) + (1)²
Hint:
49² = (50 – 1)²
= (50)² – 2(50)(1) + (1)²

Q5.	Class 8 Maths Mcq with answers The factorisation of (\(\frac{x^2}{y^2}\) -2+\(\frac{y^2}{x^2}\)) x ≠ 0, y ≠ 0 is
	A. (\(\frac{x}{y}\)+\(\frac{y}{x}\))²
	B. (\(\frac{x}{y}\)–\(\frac{y}{x}\))²
	C. (\(\frac{x}{y}\)-1)²
	D. (\(\frac{x}{y}\)+1)²

Ans: (\(\frac{x}{y}\)–\(\frac{y}{x}\))²
Hint:
\(\frac{x^2}{y^2}\) – 2 + \(\frac{y^2}{x^2}\)
= (\(\frac{x}{y}\))² – 2(\(\frac{x}{y}\))(\(\frac{y}{x}\)) + (\(\frac{y}{x}\))²
= (\(\frac{x}{y}\) – \(\frac{y}{x}\))²

Q6.	Learn Cbse Class 8 Maths Mcq The value of \(\frac{0.73×0.73×-0.27×0.27}{0.73-0.27}\) is
	A. 1
	B. 0
	C. 0.73
	D. 0.27.

Ans: 1
Hint:
Value = \(\frac{(0.73+0.27)(0.73-0.27)}{0.73-0.27}\) = 1

Q7.	Mcq Class 8 Maths Chapter 14 The factorisation of x² – 9 is
	A. (x – 3)²
	B. (x + 3)²
	C. (x + 3)(x – 3)
	D. none of these.

Ans: (x + 3)(x – 3)
Hint:
x² – 9 = (x)² – (3)² = (x – 3) (x + 3).

Q8.	Mcq for Class 8 Maths Chapter 14 The factorisation of 36x²y² – 1 is
	A. (6xy – 1)(6xy + 1)
	B. (6xy – 1)²
	C. (6xy + 1)²
	D. (6 + xy)²

Ans: (6xy – 1)(6xy + 1)
Hint:
36x²y² – 1 = (6xy)² – (1)²
= (6xy – 1)(6xy + 1).

Hint:
3x² + 10x + 8 = 3x² + 6x + 4x + 8
= 3x(x + 2) + 4(x + 2)
= (x + 2)(3x + 4).

Q12.	Ncert Class 8 Maths Mcq Questions The factorisation of 3x² – 16x + 16 is

	D. (x + 4)(3x – 4).

Ans: (x – 4)(3x – 4)
Hint:
3x² – 16x + 16
= 3x² – 12x – 4x + 16
= 3x(x – 4) – 4(x – 4)
= (x – 4) (3x – 4).
