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:

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
