Simplest method: elimination.
Subtract the first equation from the second one.
(2a+b=-33)-(a+b=-10) gets you to a=-23.
Now plug that in for a and solve.
-23 +b=-10
b=13

F(x) = x² + 4x + 10
f(x) - 10 = x² + 4x
perfect square:
x² + 4x + 4 ⇒ (x + 2)²
(x + 2)² = x(x+2) + 2(x+2) = x² + 2x + 2x + 4 = x² + 4x + 4
f(x) - 10 + 4 = x² + 4x + 4
f(x) - 6 = (x+2)²
f(x) = (x+2)² + 6
