Complete the Square – Formula
Complete the Square Formula Let’s derive the Complete the Square Formula below. The Quadratic Equation in Standard Form is \(\boxed{ y=x^2+bx+c }\) To Complete the Square we add and subtract \( \textcolor{blue}{({b \over 2})^2} \) which yields: \(\boxed{ y=x^2+bx+ \textcolor{blue}{({b \over 2})^2} + c – \textcolor{blue}{({b \over 2})^2} }\) Completing the Square yields: \(\boxed{ y=(x+b/2)^2 … Read more
