Question

factorize 15xy+15+9y+25x​

Answer 1

Answer:

Split

15xy 25x +9y - 15

into two 2-term polynomials

25x +15xy and +9y 15

This partition did not result in a

factorization. We'll try another one:

15xy 25x and +9y 15

This partition looks good

1.2

Pull out from each binomial separately

15xy 25x = 5x (3y-5)

+9y 155 = +3.(3y - 5)

1.3

Add up to arrive at the desired

factorization

(5x +3) (3y - 5)
