Question

Find the sum of these polynomials.

(5x2 - 4x + 2) + (3x2 + 9x - 8) =

Answer 1

add the terms with same variable of the same power, so
(5x^2 - 4x + 2) + (3x^2 + 9x - 8)
= 5x^2 + 3x^2 -4x +9x +2 -8
= can you try first?

Answer 2

8x2 - 5x + 10 would it be this

Answer 3

first term -> correct
second and the third term -> incorrect

Answer 4

-4x +9x = (9-4)x = ?

Answer 5

8x2 - 5x - 6

Answer 6

first term and last term => correct
second term ->incorrect

Answer 7

-4x +9x can be written as 9x-4x, what would you get for this?

Answer 8

8x2 + 5x - 6

Answer 9

yes :)
