X^2=-14x-40
Move things to where you want them.
--------------------
x^2 + 14x + 40 = 0
Hint: 40 = 4*10

We are trying to solve:
First, bring the terms on the right side of the equation to the left side by doing the opposite (add 14x and add 40 to both sides):
Now, try to factor the above expression. Since 40 = 10 * 4 and 10 + 4 = 14 (the middle term), the expression above factors into the following:
(x + 10)(x + 4) = 0
Next, we have x + 10 = 0 OR x + 4 = 0, so x = -10 or x = -4.
The solutions are -4 and -10.
