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 ...

The graph of the quadratic equation \(y = ax^2 + bx + c\) crosses the \(y\)-axis at the point \((0, c)\). The \(x\)-coordinate of any point on the \(y\)-axis has the value of 0 and substituting ...
