Quizplus · Accepted Answer

The quadratic formula $m = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ is used with $a = 5$, $b = 12$, and $c = 5$. Solving gives $m = \frac{-12 \pm \sqrt{144 - 100}}{10} = \frac{-12 \pm \sqrt{44}}{10} = \frac{-6 \pm \sqrt{11}}{5}$.

Solve - 5m2+12m+5=05 m ^ { 2 } + 12 m + 5 = 05m2+12m+5=0

Solve
- $5 m ^ { 2 } + 12 m + 5 = 0$
