solve (4y+8)(3y-2)

OpenStudy (unklerhaukus):

\[(4y+8)(3y-2)=4y(3y-2)+8(3y-2)\] \[\qquad\qquad\qquad=4y\times3y-4y\times2+8\times3y-8\times2\]

OpenStudy (raden):

to solve or to expand it ?

OpenStudy (unklerhaukus):

hmm how to solve if its not an equation?

OpenStudy (raden):

that's right @UnkleRhaukus :)

OpenStudy (anonymous):

(4y+8)(3y-2) = Use the FOIL to expand. 4y times 3y + 4y times -2 + 8 times 3y + 8 times -2 = 12y^2 -8y +24y - 16 = 12y^2 + 16y - 16 Done!
