The Greatest Common Factor (GCF) is to look for the biggest number that is simultaneously divisible into 15 and 30.

3    /       15      30

5    /       5        10

        /     1         2

GCF = 3 * 5 = 15.

The greatest common factor = 15.

I hope this explains it.

C= R

<=> 20/3x+50 = 10x (with x > 0 and x is a whole number)

Factor the polynomial by grouping : x^3+5x^2-6x-30
andrew-mc [135]

The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.

x^3+5x^2-6x-30

(x^3+5x^2)+(-6x-30)

x^2(x+5)+(-6x-30)

x^2(x+5)-6(x+5)

(x^2-6)(x+5)

-------------

Answer: (x^2-6)(x+5)
