D)-3.5, -1.3

Question

Quizplus · Accepted Answer

The quadratic formula is given by $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$, where $a$, $b$, and $c$ are coefficients from the quadratic equation $ax^2 + bx + c = 0$. For the given equation $5m^2 + 12m + 1 = 0$, $a = 5$, $b = 12$, and $c = 1$. Plugging these values into the quadratic formula gives the solutions $m = -2.3$ and $m = -0.1$, rounded to the nearest tenth.
