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

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, so the equation has no solutions. The graph of \(y = x^2 + 2x ...
