(8x (x to the 2 power) + 8x-2)-(8x (x to 2nd power) +5) = 6x+2.
(8x^2+8x-2) - (8x^2+5 )= 6x+2
8x^2-8x^2+8x-2-5=6x+2
8x-7=6x+2
2x=9
x=9/2

Clear the parentheses on the left.
Combine like terms on the left.

Subtract 6x from both sides to get all your x's on the left.

Add 7 to both sides.

Divide both sides by 2

Happy Calculating!!!

[remove the parenthesis and change the signes wherever necessary]
[combine like-terms]
8x-2-5 = 6x+2
8x-7 = 6x+2[isolate the x]
8x-7+7 = 6x+2+7 [isolate the x]
8x = 6x+9
8x-6x = 6x-6x+9
2x = 9
2x/2=9/2
x=9/2
