An alternative method to solve a quadratic equation is to complete the square ... right)^2 - c\) which can then be solved by taking the square root of both sides. Start by following the formula ...

Everyone learns (and some readers maybe still remember) the quadratic formula. It’s a pillar of algebra and allows you to solve equations ... and the square root is about 1.866.

If a quadratic ... one solution to the equation, \( x = 3\). The graph of \(y = x^2 - 6x + 9 \) touches the x-axis at \( x = 3\). It is not possible to find the square root of a negative number ...
