Question

Use the grouping method to factor the polynomial. 6x^7+48x^5+36x^4 HELP?! I'm confused.. I've never learned this..

Answer 1

What is the greatest common factor of 6, 48 and 36?

Answer 2

6

Answer 3

Yes. So we can take out a 6 from the 3 terms. How many x's can we take out?

Answer 4

Hmmm, not sure can I take out all??

Answer 5

one term has 7 x's
one term has 5 x's
one term has 4 x's
So the maximum we can take out...remember we have to take the same amount out of all of the terms.. is 4 x's
Take out 6x^4

Answer 6

6x^4(x^3 + 8x + 6)
Foil that out to check if you like, and you should get the original problem.

Answer 7

Oh okay, Thanks!!
