Question

Add the following polynomials

-4.1x^2+0.9x-9.8/1.7x^2-2.4x-1.6

Answer 1

first you need to combine like terms

Answer 2

you add -4.1x^2 and 1.7x^2 which is -2.4x^2
then you add 0.9x and -2.4x which is -1.5x
then you add -9.8 and -1.6 which is -11.4
and the answer is -2.4x^2-1.5x-11.4

Do you understand all of that? If not just tell me and I'll explain

Answer 3

And always make sure you have your exponents in order from largest to smallest

Answer 4

what about this one?

Add the following polynomials

Answer 5

what are you trying to do with those. Are there three polynomials that you are trying to add?

Answer 6

yes

Answer 7

okay hold on let me write it down

Answer 8

well first you look at all of the exponents just like we did before

you add 2x^3 and x^3 and 3x^3 which is 6x^3
then add -4x^2 and 6x^2 and 2x^2 which is 4x^2
then add 6x and 8x and -4x which is 10x
then add -3 and 12 and -7 which is 2

and the answer is 6x^3+4x^2+10x^2

Do you understand?

Answer 9

oh I messed up

Answer 10

the answer is 6x^3+4x^2+10x+2
