![]() ![]() If the equation fits the form (ax2k) or (a(xh)2k), it can easily be solved by using the Square Root Property. If the quadratic factors easily this method is very quick. The quadratic formula provides an accurate method to solve any quadratic equation, whether it has real or complex solutions. To identify the most appropriate method to solve a quadratic equation: Try Factoring first. Calculate Solutions: Substitute the values of a, b, and c into the formula and calculate the solutions for x.There are two possible solutions, one with the positive square root and one with the negative square root ( ©N v2 Y0s1h1 q 8KnuIt ia p xS2oKfwtxwqa5r7eZ pL7L 2C Z.l z NAsl gl g xrCiWgWhFtOsX yr 2eXsmeOrnvse Jd m.5 r lM 2a ad e5 zw hi 1t 5hj 0I QnZf2i Onpi8t Ie K TAhlgweObrMaX q21.Apply the Quadratic Formula: Use the quadratic formula to calculate the solutions of the equation:.Identify Coefficients: Identify the values of a, b, and c from the quadratic equation.Write Down the Equation: Start with the quadratic equation in the standard formĪx 2 + bx + c = 0, where a, b, and c are constants.These are the steps to solve a quadratic equation using the quadratic formula: Quadratic Formula (irrational solutions).Quadratic Formula (rational solutions).If we divide both sides by 4, we get: x 2 + 10x + 70.
