Question

Identify the GCF of 10x^4y^3 − 5x^3y^2 + 20x^2y.

Answer 1

GCF of 10, -5, and 20 is 5


GCF of x^4y^3, x^3y^2, and x^2y is x^2y


So the GCF of the three terms is 5x^2y

Answer 2

eplain how to completely factor 2x2 − 8x − 42.

Answer 3

find two factors of 2(-42) that have product 2(-42) and have sum -8;

2(-42)=4(-21)=12(-7)=6(-14)

-8=-14+6

-8x=-14x+6x

so replace -8x with -14x+6x and then factor by grouping
