WebIn math, a quadratic equation is a second-order polynomial equation in a single variable. It is written in the form: ax^2 + bx + c = 0 where x is the variable, and a, b, and c are constants, a ≠ 0. How do you know if a quadratic equation has two solutions? A quadratic equation has two solutions if the discriminant b^2 - 4ac is positive. WebJul 11, 2024 · Explanation: x2 = 8x −15. x2 −8x = − 15 ← leave the constant on the right side. Make a perfect square by adding ( b 2)2 to both sides. b = − 8 → ( −8 2)2 = 16. x2 −8x + 16 = − 15 +16. (x −4)2 = 1. x − 4 = ± 1. x − 4 = 1 → x = 5.
