Question

30 Points Solve for x. 8x2−3=2 x=±10√4 x=±10√2 x=±5√2 x=±5√4

Answer 1

Answer:

$x=(+/-)\frac{\sqrt{10}}{4}$

Step-by-step explanation:

we have

$8x^{2}-3=2$

adds  3 both sides

$8x^{2}=2+3$

$8x^{2}=5$

Divide by 8 both sides

$x^{2}=5/8$

square root both sides

$x=(+/-)\sqrt{\frac{5}{8}}\\ \\x=(+/-)\frac{\sqrt{5}}{2\sqrt{2}} \\ \\x=(+/-)\frac{\sqrt{10}}{4}$
