Question

Which one of the following in not a pure quadratic equation?A] x2 + 2 = 6 B] 2m2 = 72 C] p2 = 9 D] K2 = K​

Answer 1

$\huge \green{b) \: {2m}^{2} + 2 = 72}$

Answer 2

b)2m2+2=72

An equation that can be expressed in the form ax2+c=0, where a and c are real numbers and a=0 is a pure quadratic equation. Or the quadratic equation having only second degree variable is called a pure quadratic equation

One example: x2−9=0
