STATEMENT - 1 : (x−2)(x+1) = (x−1)(x+3) is a quadratic equation.

STATEMENT - 2 : If p(x) is a quadratic polynomial, then p(x) = 0 is called a quadratic equation.

A

Statement - 1 is True, Statement - 2 is True, Statement - 2 is a correct explanation for Statement - 1

B

Statement - 1 is True, Statement - 2 is True : Statement 2 is NOT a correct explanation for Statement - 1

C

Statement - 1 is True, Statement - 2 is False

D

Statement - 1 is False, Statement - 2 is True

Correct option is

D

Statement - 1 is False, Statement - 2 is True

Given equation (x−2)(x+1)=(x−1)(x+3) 

To find whether the given equation is a quadratic equation or not

Sol:

 (x−2)(x+1)=(x−1)(x+3)⟹x2+x−2x−2=x2+3x−x−3⟹x2−x2+x−2x−3x+x−2+3=0⟹−3x+1=0 

This is not a quadratic equation as an equation of degree two is called a quadratic equation.

And, a polynomial when equated to zero or some value becomes an equation.
