Question

Factor: xy+y+5x+5

Answer 1

x(y+5)+(y+5)
=(x+1)(y+5)

Answer 2

How?

Answer 3

That's all there is to it, except maybe a first step like this:
xy+y+5x+5
= xy + 5x + y + 5

Answer 4

Thank you!

Answer 5

xy+y+5x+5 = y( x + 1) + 5 (x + 1)

Think of (x + 1) as a common factor (which it is) in the way you think of 33x + 33 as having a common factor of 33.

Factor out the (x + 1).

y( x + 1) + 5 (x + 1) =

( x + 1) (y + 5)

Answer 6

xy+y+5x+5
y (x +1) + 5 ( x + 1)
(x + 1) ( y + 5)
