The quadratic formula for a quadratic equation ... so the equation has no real solutions. The graph of \(y = x^2 + 2x + 5\) does not cross or touch the x-axis as the equation \(x^2 + 2x + 5 ...

When asked to solve a quadratic equation, we are really finding the roots – where the parabola cuts the x-axis, therefore when we have the graph drawn, it is very easy to do this. Looking at the ...
