I’m sure you remember the quadratic formula: x = −b±b2−4ac2a size 12{ { { - b +- sqrt {b rSup { size 8{2} } - 4 ital "ac"} } over {2a} } } {}. Back when we were doing quadratic equations, if we wound up with a negative number under that square root, we just gave up. But now we can solve these equations! Use the quadratic formula to solve: 2 x 2 + 6 x + 5 = 0 . Use the quadratic formula to solve: x 2 - 2 x + 5 = 0 . Check one of your answers to #2. Solve by completing the square: 2 x 2 + 10 x + 17 = 0 . aIn general, what has to be true for a quadratic equation to have two non-real roots? bWhat is the relationship between the two non-real roots? cIs it possible to have a quadratic equation with one non-real root?
