Solve 2 a 2 − 5 a − 25 = 0 by factoring. Enter your answers below a = or a =

kaheart [24]

Answer:

a=5, a=-2.5

Step-by-step explanation:

<em>Given:</em>

<em /> $2 a^2 - 5 a - 25 = 0$

<em>Solution:</em>

<em /> $a_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-25\right)}}{2\cdot \:2}$

$a_{1,\:2}=\frac{-\left(-5\right)\pm \:15}{2\cdot \:2}$

$a_1=\frac{-\left(-5\right)+15}{2\cdot \:2},\:a_2=\frac{-\left(-5\right)-15}{2\cdot \:2}$

$a=5,\:a=-2.5$
