learn how to solve quadratic equations by completing the square when solving a quadratic equation by completing the square we first take the constant ter. Solving by completing the square higher some quadratics cannot be factorised an alternative method to solve a quadratic equation is to complete the square to solve an equation of the form . Steps for completing the square method suppose ax 2 bx c 0 is the given quadratic equation then follow the given steps to solve it by completing square method write the equation in the form such that c is on the right side if a is not equal to 1 then divide the complete equation by a such that co efficient of x 2 is 1. Solving a quadratic equation by taking the square root involves taking the square root of each side of the equation because this equation contains a non squared bi x in bo6bi x that technique wont work factoring on the other hand involves breaking the quadratic equation into two linear equations that are both equal to zero unfortunately trying to factor this equation
