Answer 1

So, it's just foiling sort of

Answer 2

when you use FOIL, you are essentially distributing each term of a polynomial to another

Answer 3

does it need to have like variables?

Answer 4

oh oh oh wait, I thought that was a multiplication sign. Nope this is even easier

Answer 5

\[(7x2y+6xy2−3xy)−(4x2y−2xy2+5xy)\] Correct?

Answer 6

yes

Answer 7

ok so can you find the like terms? The terms with the exact same variable combinations?

Answer 8

first we distribute the -ve sign?

Answer 9

yes you can

Answer 10

please do

Answer 11

hang on i'm solving :)

Answer 12

okee dokey

Answer 13

and just because this bothered me, here we go \[(7x^2y+6xy^2−3xy)−(4x^2y−2xy^2+5xy)\]

Answer 14

\[(3x^2y+8xy^2-8xy)\]
:D
