Question

add the polynomials
-9X To the second +4x
2x To the second _ 8x-6

Answer 1

Btw, it's not: to the second, it's squared

so we have

-9x^2 + 4x
being added to 2x^2 - 8x - 6

let's put them side by side

-9x^2 + 4x + 2x^2 - 8x - 6

can you add the like terms?

-9x^2 + 2x^2 = ?
4x - 8x = ?

Answer 2

84+-4?

Answer 3

no, remember:

-9x^2 + 2x^2 = (-9 + 2)x^2 = ??
4x - 8x = (4 - 8)x = ??
