# How do you factor x(b-5)+z(b-5) ?

May 30, 2016

(b - 5)(x +z)

#### Explanation:

There is a common factor of (b -5) in the 2 terms which can be taken out.

When (b - 5) is taken out of the 1st term we are left with x.

Similarly, when (b -5) is taken out of the 2nd term we are left with z.

hence (b -5)(x + z) are the factors.
