Do you wish to solve for x?
Here's a way to go about this:
x^2 + 8x + 32 = 11
Note: I'm using ^2 to mean squared.
First, set the equation to 0 by subtracting 11 from both sides of the equation (whatever operation you do to one side of an equation you must do to the other side as well):
x^2 + 8x + 32 - 11 = 0
x^2 + 8x + 21 = 0
Since this doesn't factor easily, you will have to use the quadratic formula to solve for x:
x = [-b ± √(b^2 - 4ac)]/(2a)
In this case, a = 1, b = 8 and c = 21
I'll let you take it from here.
I hope this helps and is what you were asking.
