Usually, you would find two numbers that multiply to 12 (c) and add to make 2 (b).
However, there are not any nice numbers that work, so you must use the quadratic formula.
x = -b ±√b2 - 4ac
___________
2a
where a = 1 b = 2 and c = 12 if the expression is x2 + 2x + 12
The square root in the equation is over b2 - 4ac.
Solve for x, and then put in factored form : (x - root1)(x - root2)
