Question

(2x^7 + 4x^4 - 2x + 3) - (4x^4 - 2x^3 + 3) =

A. 2x^7 + 8x^4 + 2x^3 - 2x
B. 2x^7 + 2x^3 - 2x
C. 2x^7 - 2x^3 - 2x
D. 2x^7 + 8x^4 - 2x^3 - 2x

Answer 1

first distribute the negative through the parenthesis and you will get :
2x^7 + 4x^4 - 2x + 3 - 4x^4 + 2x^3 - 3
now lets combine like terms..
2x^7 + 2x^3 - 2x

Answer 2

do you have any questiona at all ?

Answer 3

the two 4x^4 cancels out.?

Answer 4

yes

Answer 5

okay thanks i got it now

Answer 6

if it makes it easier...seperate them
2x^7 -- no other like term
4x^4 - 4x^4 = 0
2x^3 -- no other like term
-2x -- no other like term
3 - 3 = 0
now just write the results..
2x^7 + 2x^3 - 2x
