Question 410830: I am learning polynomials but have new clue how to solve with problems like this. this is the foil method.
(11x+3y)(x+4y)
Answer by angelagallegos(8)   (Show Source):
You can put this solution on YOUR website! Foil stands for F-first, O-outer, I- inner, L- last
what this means is that you are going to multiply the first terms in both parts
F (11x)(x)=11x^2
O (11x)(4y)=44xy
I (3y)(x)= 3xy
L (3y)(4y)= 12y^2
this would give you 11x^2+44xy+3xy+12y^2
now check to see if you have same terms if you do add them together.
So, 44xy+3xy =47xy
Answer= 11x^2+47xy+12y^2
hope this helps!
