jhonyy9 (jhonyy9):
this wann to be (3x+2y) squared ?
OpenStudy (anonymous):
yea
OpenStudy (anonymous):
9x2-4y2 9x2+4y2 9x2+12xy+4y2 None of the above
OpenStudy (anonymous):
its one of these
jhonyy9 (jhonyy9):
so than multiply (3x+2y)(3x+2y)=9x2 +6xy +6xy +4y2 = 9x2 +12xy +4y2

jhonyy9 (jhonyy9):
ok ?
OpenStudy (anonymous):
uhhhh im a little lost
OpenStudy (anonymous):
none of the above, i think
OpenStudy (anonymous):
(3x+2y)^2=9x^2+4y^2+12xy
OpenStudy (turingtest):
how is this simplification? seems like expanding makes it less simple to me...

anyway, do what jhonyy did and multiply (3x+2y)(3x+2y) using the FOIL method.
