try this, these examples will assist you. Solve the following equation via factorization i. 6x2 = 18x ii. 15x2 + 16x = 15 Solutions i. 6x2 = 18x 6x2 - 18x = 0    (step 1)                        6x(x - 3) = 0    (step 2)                        6x = 0  (step 3)                        And x - 3 = 0 ∴ x = 0 or x = 3            (by step 4)       ii. 15x2 + 16x = 15 15x2 + 16x - 15 = 0     (step 1)                       (5x - 3) (3x +5) = 0      (step 2)                        (5x - 3) = 0} Step 3                                                                  {3x + 5 = 0} ∴ x = - 5/3 or +3/5      (step 4) Posted by isbell | Posted Date: 2/12/2013 2:20:51 AM
