<h3>What is a Quadratic Equation ?</h3>

Quadratic equations are polynomials of degree 2 , It is represwented by ax² + bx +c = 0.

The quadratic equation given is

x² -9x +2 = 0

x² -9x + (81/ 4) - (81/4) + 2 = 0

x² -9x + (9/2)² - (81/4) +2 = 0

(x - 9/2)² - (73/4) = 0

Therefore , 81/4 will be added to complete the square to solve the quadratic equation.
