Answer:
Doing the Foil Method.
Example: (6x+5y)(2x+3y)
The foil stands F is for First, O is for outside, I is for inside and L is for last.
First: the first on the first (6x+5y) then multiply it on the another first number on the second (2x+3y) answer: (6x)(2x)= 12x²
Outside: Get the both number that are on the both side
Answer: (6x)(3y)= 18xy
Inside: Get the number on the inside (5y)(2x)= 10xy
Last: On the last (5y)(3y)= 15y²
Then you will combine all the same term but it depends on sign
12x²+18xy+10xy+15y²
so equals 12x²+28xy+15y²
OR Just Combine All same term to have trinomial form.
