Title: What does it mean to solve an equation by factoring? Post by: oaqadir on Sep 7, 2012 Alright so basically, in my math homework it says "find the factors" and I did that, UNTIL a new section of my homework says"Solve the equation by factoring"
The teacher said to do something else AFTER I factor but I forget! For example x^2-6x-7=0 is obviously (x+1)(x-7) And x^2+x=6 is (x+3) (x-2) Soo... What do I do?! I found the factors but what do I have to do when it says "Solve the equation by factoring?" PLEASE EXPLAIN! THANK YOU! Title: What does it mean to solve an equation by factoring?

( x + 1 ) ( x - 7 ) = 0 x = - 1 , x = 7 x ² + x - 6 = 0 ( x - 3 ) ( x + 2 ) = 0 x = 3 , x = - 2 |
