... The only possible combination of numbers is 9 and -5, so x2 + 4x – 45 = 0 becomes (x + 9)(x – 5) = 0. And you would set each piece equal to zero to solve for x. BUT, let’s suppose we have the equation x2 = 25. Intuition says that to isolate the variable, we use the inverse operation of the square ro ...
