Question 209266: how is this problem done on factoring
x^2-4x-60
Answer by 20062042(2) (Show Source):
You can put this solution on YOUR website! The idea with factoring is finding two numbers, so that when added they equal 'b' (which is -4) and when multiplied they equal 'c' (which is -60).
The two numbers I got were -10 and 6. So put the numbers in this form:
(x-10)(x+6)
(notice that when you multiply this out again, using FOIL, you will get your original equation!)
Then set each one equal to zero
(x-10)=0
x=10
(x+6)=0
x=-6
Your answers are x=10 and x=-6
I hope this helps!
