5 x - x y + 15 - 3 y

Solution

- (y - 5) (x + 3)

Solution steps

5 x - x y + 15 - 3 y

= (- x y + 5 x) + (- 3 y + 15)

Factor out

- x

from

- x y + 5 x : - x (y - 5)

- 3

from

- 3 y + 15 : - 3 (y - 5)

= - x (y - 5) - 3 (y - 5)

Factor out common term

y - 5

= (y - 5) (- x - 3)

Factor

- x - 3 : - (x + 3)

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

Apply rule:

a (- b) = - ab

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

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