Question
Solve the following quadratic equation by factorization.
25m2 = 9
25m2 = 9
✓
Answer
$\begin{array}{l}
25 m ^2=9 \\
\Rightarrow m ^2=\frac{9}{25} \\
\Rightarrow m =\sqrt{\frac{9}{25}} \\
\Rightarrow m = \pm \frac{3}{5} \\
\text { Hence, } m = \pm \frac{3}{5} \text { are roots of the equation. }
\end{array}$
Hence, $m = \pm \frac{3}{5}$ are roots of the equation.
