Question

select the difference, (6x^2-7x^3)-(4x^2-9x^3)

Answer 1

\[6x^2-4x^2 = ?\]\[-7x^3-(-9x^3) = ?\]

Answer 2

2x^2(1+x)

Answer 3

\[2x ^{2}(1+x)\]

Answer 4

Since they have the same exponents - you can just add/subtract the terms

Answer 5

I Already have the answer right ?

Answer 6

that isn't any of my answers, as following, A.) 4x^6 B.) 4x^5 C.) 2x^2-16x^3 D.) 2x^2+2x^3

Answer 7

Please refer to what I posted.

Answer 8

thanks

Answer 9

it is D

Answer 10

You're welcome, technically, the answer she gave was also correct, but it was in the factored form of the answer

Answer 11

whatever...it was a multiple choice question..so

Answer 12

it is D

Answer 13

So i was wrong?

Answer 14

yes because you have to combine like terms

Answer 15

In terms of the question being asking, yes. but, 2x^2+2x^3 factored is 2x^2(x+1). It's the same value, but the question didn't want it in factored form

Answer 16

I Had it right, it was just factored but if u simpily if u get \[2x ^{2}+2x ^{3}\]

Answer 17

oh ok
