+23 How To Solve Quadratic Equations By Completing The Square With Coefficients 2022

If The Coefficient Of X 2 Is 1 (A = 1), The Above Process Is Not Required.

In the method completion of square we simply add and subtract ( 1 2 c o e f f i c i e n t o f x) 2 in lhs. In this method we create square on lhs and rhs and then find the value. Note that the quadratic equations in this lesson have a coefficient on the squared term, so the first step is to get rid of the coefficient on the squared term by dividing both sides of the equation by this coefficient.
