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

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

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

If we divide it from 2 in both sides

$\frac{2(5x+2)^2}{2}=\frac{48}{2}$

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

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

$x=\frac{2\sqrt{6}-2 }{5} or x=\frac{-2\sqrt{6}-2}{5}$  :  Answer
