Question

x4 -3x + 1, 4x2 - 2x + 8, and x3 - 9

Answer 1

what's the question? you're just giving numbers here

Answer 2

Add the following polynomials, then place the answer in the proper location on the grid. Write your answer in descending powers of x.

Answer 3

forget about the "answer in the proper location on the grid" part

Answer 4

do you know what like terms are ?

Answer 5

i just want the answer

Answer 6

Basically take the numbers with the same amount of x's and add them but pay attention to the signs

Answer 7

Like x^4 cant be added to x^3, but -3x and -2x can be

Answer 8

x^4 + 0x^3 + 0x^2 -3x + 1
0x^4 + 0x^3 + 4x^2 - 2x + 8
0x^4 + 1 x^3 + 0x^2 -0x - 9
----------------------------add
x^4 + x^3 + 4x^2 - 5x

Answer 9

@texaschic101 is right, and then you factor out the x

Answer 10

final answer would be x(x^3+x^2-4x-5)
check my work?

Answer 11

like terms : 3x + 2x - x
unlike terms : x^2 + 4x

you cannot add/subtract unlike terms

Answer 12

what sloth said....with the factoring out the x...that is correct, but your teacher might not want it factored. Make sure before you turn it in

Answer 13

thank you both

Answer 14

sure thing :)

Answer 15

no problem
