Question

is anyone in algebra that can help me with polynomials?

Answer 1

what do you need help with

Answer 2

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

Answer 3

add like terms

Answer 4

well yeah.. but i dont know how to start.

Answer 5

start by getting rid of the parenthesis
and distribute the negative signs

Answer 6

first find the like terms
\(2x^2\) and \(x^2\) are like terms because they both have \(x^2\)

Answer 7

and then there is 3x
which term is like that?

Answer 8

x?

Answer 9

-x
so 3x and -x are like terms
how about -4 ?

Answer 10

-2

Answer 11

so add like terms

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

Answer 12

okay i got it now how do i put it together?

Answer 13

what did you get?

Answer 14

3x^2, 4x, -2

Answer 15

ok so
\(3x^2,2x,-2\)
put it together
\(3x^2+2x-2\)
