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 ...

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 ...
