Question

Please answer numbers 32 and 33! Please show work and explain your answer!

Answer 1

12.
Add like terms from both trinomials:


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

`2x + -5x = -3x`

`-1 + 3 = 2`

Combine these terms to get a new trinomial as your answer:


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


13.
Subtract like terms from both trinomials (note that subtracting a negative is the same as adding it as a positive):


`3x^(2) - 5x^(2) = -2x^(2)`

`-8x - -11x = -8x + 11x = 3x`

`-1 - -1 = -1 + 1 = 0`

0 can be left out of the answer.

Combine these terms to get a binomial as your answer:


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