Please solve: (10x-4y) (3x+2y)
In order to solve we must use the FOIL method. FOIL stands for first, outside inside, and last. This is how we will solve this binomial. 10x*3x is our first binomial and it equals 30x^2 10x *2y is our outside binomial it equals 20xy 4y*3x is our inside binomial it equals 12xy 4y*2y is our last binomial it equals to 6y^2 Let's put these together 30x^2 +20xy-12xy+6y^2 Combine the middle binomials and solve 30x^2 +8xy+6y^2
