thanks

OpenStudy (nubeer):

no problem :)

for this one is it the same thing y^3+7y^2-5y-35

OpenStudy (nubeer):

yes its same just see what u can take common or how can u make factors common..

OpenStudy (anonymous):

we can take factor 5y

OpenStudy (nubeer):

hmm or maybe look for soemthing else y^3 + 7y^2 look what u can take common in this part?

OpenStudy (anonymous):

y^2

OpenStudy (raden):

maybe like this : y^3+7y^2-5y-35 = y^3-5y+7y^2-35 =y(y^2-5) + 7(y^2-5) = ......

OpenStudy (raden):
