How to solve harder quadratics

Factorising quadratics when the coefficient of x squared ≠ 1

WebTo solve the quadratic equation using completing the square method, follow the below given steps. Now, divide the whole equation by a, such that the coefficient of x 2 is 1. Let us understand with the help of an example. Example: Solve 4x 2 + x = 3 by completing the square method. Divide the whole equation by 4. WebTo solve this, you would use the zero product property. If you make one of the parentheses equal to zero then the whole left side is equal to zero (because zero multiplied by anything is zero). So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2.
