The equation x 2 + 3 x − 4 = 0 looks like: where the solutions to the quadratic formula, and the intercepts are x = − 4 and x = 1 . Now you can also solve a quadratic equation through factoring, completing the square, or graphing, so why do we need the formula?
Trinomial. Quadratic equation. The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side. A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root.
