x squared + 8x + 32 = 11

Answer 1

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.
