Question

Solve for x if 2(5x + 2)2 = 48.

Answer 1

its answer C

x=-2+2sqrt6/5 and x=-2-2sqrt6/5

Answer 2

Explanation:

Alright, lets get started.

The given equation is :

`2(5x+2)^2=48`

If we divide it from 2 in both sides

`(2(5x+2)^2)/(2)=(48)/(2)`

`(5x+2)^2=24`

Taking square root on both sides

`(5x+2)=`±24

`(5x+2)=`±2√6

Subtracting 2 in both sides

`5x=`±2√6-2

Dividing 5 in both sides

`x=(2√(6)-2 )/(5) or x=(-2√(6)-2)/(5)` : Answer
