Question
Solve the following quadratic equation by factorization.
$m^2-11=0$
$m^2-11=0$
✓
Answer
$m ^2-11=0 $
$\Rightarrow m ^2=11 $
$\Rightarrow m =\sqrt{11}$
$\Rightarrow m = \pm 11$
Hence,$m= \pm 11$ are roots of the equation.
$\Rightarrow m ^2=11 $
$\Rightarrow m =\sqrt{11}$
$\Rightarrow m = \pm 11$
Hence,$m= \pm 11$ are roots of the equation.
