Completing the square

Rewriting a quadratic using a squared bracket, such as $x^2+6x+5=(x+3)^2-4$.

Rewriting a quadratic in the form $a(x-h)^2+k$, which displays its turning point directly.

The process of rewriting a quadratic expression in the equivalent form $a(x+p)^2+q$.

A method that rewrites a quadratic using a squared bracket, such as $(x-p)^2+q$.
