Solve by factoring 12t^2 + 17t = 40

OpenStudy (anonymous):

t(12t+17)=40

OpenStudy (anonymous):

hmm...well I got this from wolframalpha..I couldnt think of the factors that would sum to 17 but when multiplied equal to 40

OpenStudy (anonymous):

12t^2 + 17t - 40

I can present a factored solution, but it's not worth it.

OpenStudy (anonymous):

(8+3 t) (-5+4 t)

hero (hero):

Steps?

OpenStudy (anonymous):

I use the criss cross method
