Question

Simplify the expression.
8x5+2x7
--------
2(7-4)

Answer 1

you need to find the GCF of 8x^5 and 2x^7
this is the highest term which divides into these 2 terms
can u do this?

Answer 2

first find GCF of 2 and 8 - that is 2
now how about x^5 and x^7?

Answer 3

its x^5 because x^7 / x^5 = x^2 and x^5 / x^5 = 1

so GCF is 2x^5

now you can factor the top of the fraction by taking 2x^5 out
r u ok with that?

Answer 4

nope
