Question

7) For what value of 'a' the equation (a-2)x² + 2x + 3 = 0 will not be a quadratic equation?​

Answer 1

Explanation:

A quadratic equation is the equation which has polynomials of degree 2.

Here, if $\mathsf{(a-2)x^2+2x+3=0}$ is not a quadratic equation, it means that the term $\mathsf{x^2}$ doesn't exist, or in other words, has its coefficient as 0.

This means that

$\mathsf{a-2=0}$

∴ $\mathsf{a=2}$

Answer: a = 2

I hope this helps. :D
