# completing the square

## Summary

Completing the square is a technique used to factor quadratics, rewrite them in the form (x + a)2 + b, and solve quadratic equations. It involves taking half of the coefficient of a term, squaring it, and adding it to both sides of the equation. This technique is useful for solving quadratics, as it can help to find the solution to the equation and reduce the number of variables involved. 1 2 It is also used in graphing quadratic functions, evaluating integrals in calculus, and finding Laplace transforms. 3
