Question

can someone help me (5+5x3-7x4) + (x+3x3-4x4-8)=
4
3

Answer 1

the 4 and the 3 is squared to the power

Answer 2

do you mean: \((5+5x^3-7x^4)+(x +3x^3-4x^4 - 8) = 4^3\)

Answer 3

no we are doing polynomial

Answer 4

I did write a polynomial....
I am not sure what your question is asking, can you take a screenshot or use the draw tool?

Answer 5

yes

Answer 6

OH that makes more sense, thank you

Answer 7

In this problem, we want to "combine like terms"

the variables that have the same degree value are considered "like terms"

Answer 8

so we can combine:

\(-7x^4\) with \(-4x^4\) because they are both x to the fourth power

Answer 9

what would you get if you added those two values?

Answer 10

−11x^4

Answer 11

awesome :)

Answer 12

i have to answer quickly i have 11 minutes left on the test

Answer 13

then combine \(5x^3\) with \(3x^3\) because they both have x to the third power

Answer 14

we can't help on timed tests. it is against our anti-cheating policy

Answer 15

I would like to point out that most of what you have is correct except for the negative in front of the 11 that we just got

Answer 16

oh ok sorry

Answer 17

no problem, I understand you're new here - feel free to ask any homework problem in the future :)

Answer 18

(5+5x3-7x4) + (x+3x3-4x4-8)=43
5+5x ^3-7x^4+ x +3x^3-4x^4-8=43
-11x^4+8x^3+x-3=43
-11x^4+8x^3+x-3-43=43
-43
-11x^4+8x^3+x-46=0
