INEED MATH HELP BADLY PLEASE HELP

CAN SOMEONE PLEASE HELP ME WITH MY SQUARE ROOT AND FOILING PLEASE?

FOIL is just distributive property of multiplication
(a+b)(c+d) = ac + ad + bc + bd
proof with distributive property:
(a+b)(c+d) = a(c+d) + b(c+d)
= ac + ad + bc + bd 
[ãv(2x+2)  ãv(x3)][ãv(2x+2)  ãv(x3)] = 4

I do not understand your special symbols but perhaps they are radical signs?
If so then
[ sqrt(2x+2)  sqrt (x3) ] [sqrt(2x+2) sqrt (x3) ] = 4
sqrt (a) sqrt (a) = a
so
(2x+2)  2 sqrt (2x+2) sqrt(x3) + (x3) = 4
or
3 x 2 sqrt (2x+2) sqrt(x3) = 5
or
(3 x 5)/2 = sqrt (2x^2 4 x  6)
square both sides
(9 x^2 30 x +25)/4 = 2 x^2 4 x  6
or
9 x^2  30 x + 25 = 8 x^2  16 x  24
or
x^2 14 x + 49 = 0
(x7)(x7) = 0
x = 7 
Thank you.

x 1 when x=3
