![]() ![]() This is the same as factoring out the value of a from all other terms. To complete the square when a is greater than 1 or less than 1 but not equal to 0, divide both sides of the equation by a. To use the Quadratic Formula, we substitute the values of a, b, and c from the standard form into the expression on the right side of the formula. ![]() Remember you will have 2 solutions, a positive solution and a negative solution, because you took the square root of the right side of the equation.Ĭompleting the Square when a is Not Equal to 1 The solutions to a quadratic equation of the form ax2 + bx + c 0, where a 0 are given by the formula: x b ± b2 4ac 2a. Isolate x on the left by subtracting or adding the numeric constant on both sides. ![]()
