Answer
False
Work Step by Step
Consider the expression
\[{{x}^{2}}+x+20\]
where,\[a=1,\ b=1,\text{ and }c=20\]
The solution of this quadratic expression can be determined by the quadratic formula\[\begin{align}
& x=\frac{-b\pm \sqrt{{{b}^{2}}-4ac}}{2a} \\
& =\frac{-1\pm \sqrt{1-4\times 1\times 20}}{2} \\
& =\frac{-1\pm \sqrt{1-80}}{2} \\
& =\frac{-1\pm \sqrt{-79}}{2}
\end{align}\]
The solution is a complex number. Therefore, the given statement is false.
