ANSWER:

This is a quadratic equation. It's power is 2.

STEP BY STEP INSTRUCTIONS

${x}^{2} + 7 = 0$

${x}^{2} = - 7$

$x = \sqrt{ - 7}$

LET US FIRST UNDERSTAND WHAT IS A QUADRATIC EQUATION :-

In algebra, a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term.

If we follow each conditions given above we can determine the quadracity of an equation.
