This is the same as factoring out the value of a from all other terms. Quadratic equations have an x2 term, and can be rewritten to have the form: a x 2 + b x + c 0 Need more problem types Try MathPapa Algebra Calculator Show Keypad Solve your quadratic equations step-by-step Solves by factoring, square root, quadratic formula methods. 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. We have two factors when multiplied together gets 0. We find that the two terms have x in common. Just like numbers have factors (2×36), expressions have factors ( (x+2) (x+3)x2+5x+6). We can factorize quadratic equations by looking for values that are common. 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 Middle School Math Solutions Polynomials Calculator, Factoring Quadratics.
