This is how the solution of the equation 2 x 2 − 12 x + 18 = 0 goes: 2 x 2 − 12 x + 18 = 0 x 2 − 6 x + 9 = 0 Divide by 2. ( x − 3) 2 = 0 Factor. ↓ x − 3 = 0 x = 3. All terms originally had a common factor of 2 , so we divided all sides by 2 —the zero side remained zero—which made the factorization easier.
