What is the completely factored form of this polynomial? 18x3-120x2-42x
Write the greatest common factor (GCF) first, and write all factors in standard form.

Step-by-step explanation:

The greatest common factor between 18, 120, and 42 is 6, and the greatest common factor between x³, x² and x is x, so

Factoring this out, we get the product

From here, we can split the -20x in the middle of the second expression into a -21x and an x:

And factor:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
