Question

Couple of GFC questions?
What is the Greatest Common Factor of x^6 and x^4?
Factor completely: 6x - 18?
Factor completely: 5x^2 + 20x?

Answer 1

x^4
6(x-3)
5x(x+4)
Do you understand how these were obtained?

Answer 2

umm no

Answer 3

ooh nevermind i see

Answer 4

thank you

Answer 5

GCF (Greatest Common Factor) Looking at X^6 and x^4 you are to determine the largest common factor in those two values. Since x^4 is contained with in x^6 (x^4)(x^2) and of course it is in x^4 (x^4*1) then x^4 is the largest common factor. Just like 8 and 2 the GCF is 2. 12, 3 GCF is 3 etc.

Answer 6

Oh good luck then with these.
