5ab+3ay+5b+3y = (a+1)(5b+3y)5ab+3ay+5b+3y=(a+1)(5b+3y)

Explanation:

Factor by grouping:

5ab+3ay+5b+3y = (5ab+3ay)+(5b+3y)5ab+3ay+5b+3y=(5ab+3ay)+(5b+3y)

color(white)(5ab+3ay+5b+3y) = a(5b+3y)+1(5b+3y)5ab+3ay+5b+3y=a(5b+3y)+1(5b+3y)

color(white)(5ab+3ay+5b+3y) = (a+1)(5b+3y)5ab+3ay+5b+3y=(a+1)(5b+3y)
