Answer 1

x = ± 10/4

Explanation:

I took the quiz

Answer 2

`x=(+/-)(√(10))/(4)`

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{(5)/(8)}\\ \\x=(+/-)(√(5))/(2√(2)) \\ \\x=(+/-)(√(10))/(4)`
