An alternative method to solve a quadratic equation is to complete the square. To solve an equation of the form \(x^2 + bx + c = 0\) consider the expression \(\left(x + \frac{b}{2}\right)^2 + c\).
An alternative method to solve a quadratic equation ... 2 = \left(\frac{b}{2}\right)^2 - c\) which can then be solved by taking the square root of both sides. Solve \(x^2 + 6x - 10 = 0\) by ...
