Question 570781: How do I factor a trinomial? I have seen many examples of this problems but i still dont understand, the problem is, -6s2 - s - 5. Can you help me? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! -6s2 - s - 5
The coffecient of s^2=-6
The coefficient of third term is -5
Multiply both you get 30
You have to split this number (30)into two parts such that when you add them you get the coefficient of the middle term which is -1
Factorize 30
the prime factors are 2*3*5
From the factors you get, combine the factors. For example 2& 3 , & 5
2*3=6
& 5
5-6=-1
That is the coefficient of the middle term
So you can now write
-6s^2-6s+5s-5
-6s(s-1)+5(s-1)
(s-1)(5-6s)
