Answer

The solutions of \[a{{x}^{2}}+bx+c\], \[a\ne 0\], are given by \[x=\frac{-b\pm \sqrt{{{b}^{2}}-4ac}}{2a}\]called the quadratic formula.

Work Step by Step

Consider the expression \[a{{x}^{2}}+bx+c\], where\[a\ne 0\] The solution of this quadratic expression can be determined by the quadratic formula\[x=\frac{-b\pm \sqrt{{{b}^{2}}-4ac}}{2a}\]
