Mathematics Class 10th Chapter-2 [Polynomials] Important 50 MCQ Question Answer

Mathematics Class 10th Chapter-2 [Polynomials]


Que 1.) If a polynomial (p(x) = x3 - 3x2 + 5x - 2) is divided by (x-1), the remainder is:
A) 0
B) 1
C) 2
D) -2

Answer: Option B (1) = Using Remainder Theorem:let's check: p(1) = 1 -3 +5 -2 = 1. So remainder is 1


Que 2.) Which of the following is a factor of (x2 + 5x + 6)?
A) (x + 2)
B) (x - 3)
C) (x + 4)
D) (x - 2)

Answer: Option A (x+2) = Factorisation: x2 + 5x + 6 = (x+2)(x+3)


Que 3.) The degree of the polynomial (7x4 - 3x3 + 2x2 - x + 5) is:
A) 1
B) 2
C) 3
D) 4

Answer: Option D (4)


Que 4.) The sum of zeroes of the polynomial (2x2 - 7x + 3) is:
A) 7/2
B) -7/2
C) 7/3
D) -3/2

Answer: Option A = Sum of zeroes = (-b/a = -(-7)/2 = 7/2)


Que 5.) If one zero of the polynomial (x2 - 5x + 6) is 2, the other zero is:
A) 3
B) -3
C) 5
D) -2

Answer: Option A = Product of zeroes = c/a = 6/1 = 6, so other zero = 6/2 = 3
