Given that F(x) = X^2 - 10X + 17. Write F(x) in the form of (x+a)^2 + b = 0, where a, & b are constants.

So we know that our equation is: X 2 - 10X +17 = 0. STEP 1: rearrange this equation to get x on one side: X 2 - 10X = -17. Lets call this, "equation 1". STEP 2: Understand that (X + a) 2 = X 2 + 2a...
