Factor 3ax-15a+x-5

$3 a x - 15 a + x - 5$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(3 a x - 15 a) + x - 5$

Factor out the greatest common factor (GCF) from each group.

$3 a (x - 5) + 1 (x - 5)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $x - 5$ .

$(x - 5) (3 a + 1)$
