(4x + 3)2 = 18
----------------------------
Distribute
(4x)(2)+(3)(2)
8x+6=18
----------------------------------
Subtract 6 on each side
8x+6-6=18-6
8x=12
--------------------------------------
Now, Divide by 8
8x ÷ 8 = 12 ÷ 8
x = 3/2 or 1.5
--------------------------------------------
x = 3/2 or 1.5 should be your answer
