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. Solve \(x^2 + 6x - 10 = 0 ...

It is not possible to find the square root of a negative ... or touch the \(x\)-axis so the equation \(x^2 + 2x + 5 = 0\) has no roots. The graph of the quadratic equation \(y = ax^2 + bx ...
