Question

Chase solved the quadratic equation x2 + 10x - 5 = 0 using the quadratic formula.
Finish solving for x. What are the solutions in simple radical form.

Answer 1

Answer:

B

Step-by-step explanation:

$\sqrt{120}$ = $\sqrt{4}$·$\sqrt{30}$ = 2$\sqrt{30}$

[(-10 ± $\sqrt{120}$) / 2] which simplifies to be (-10 ± 2$\sqrt{30}$)/2

[(-10 ± 2$\sqrt{30}$)/2] can be simplified to be -5 ± $\sqrt{30}$
