Question

What is the sum of the polynomials (-x^2+9)+(-3x^2-11x+4)

Answer 1

You can just add the terms:

(-x^2+9)+(-3x^2-11x+4) = -4x² - 11x + 13

Answer 2

`-4x^(2) -11x+13`

Explanation:

Step to add the integers.

When we add two positive integers,we add integers and +sign is used.

When we dd two positive integers, we add subtract integers, and greater integer sign is used.

When we add two negative integer, we add integers and -sign is used.

=(
`-x^(2) +9^{}`)+(
`-3x^(2) -11x^{} +4^{}`)

=
`-x^(2) +9-3x^(2) -11x+4`

=
`-x^(2) -3x^(2) -11x+9+4`

=
`-4x^(2) -11x+9+4`

=
`-4x^(2) -11x+13`
