Question

6s^2-5s-6

I ended up with (6s-3)(s-2) but it says it is not right??

anonymous · Answer

3x2=6 and -3 -2 equal -5

jim_thompson5910 · Answer

Check:


(6s-3)(s-2)


6s^2-12s-3s+6


6s^2-15s+6


So it does not work

anonymous · Answer

No, the right answer is (3s+2)(2s-3)

jim_thompson5910 · Answer

Correct factorization 


6s^2-5s-6 


6s^2-9s+4s-6 


3s(2s-3)+2(2s-3) 


(3s+2)(2s-3)

anonymous · Answer

what the eff.. so i did do it right but got the signs backwards?

anonymous · Answer

its (3s+2)(2s-3)

jim_thompson5910 · Answer

Multiply the first and last coefficients to get 6*6 = 36


So you're looking for 2 numbers that multiply to 36 and add to -5: They are -9 and 4


So break up -5s into -9s+4s and factor by grouping
