Answer:
(x+8)^2=40
Explanation:
x^2+16x+24=0.
Well, to solve for this, you do:
1. (16/2)^2 to find what number should be in place of 24.
That, by the way, is 64.
2. There's no 64! We have to add 64-24 on both sides, which makes the equation
x^2+16x+64=40.
3. Since we know that (16/2)=8, using the completing the square formula, you know that it's going to be a variation of (x+8)^2 or (x-8)^2.
As we are adding for the middle term, it must be (x+8)^2.
4. Answer: (x+8)^2=40.
Sorry if this is too late :)
