Question

(−x3+26x2−7x−13)+(6x4−x3+8x+27)



Express the answer in standard form.

Answer 1

I believe the answer is 6x^4 −2x^3 + 26x^2 −15x + 14

Answer 2

`6x^4-2x^3+26x^2+x+14`

Explanation:

The expression to simplify (add) is
`(-x^3+26x^2-7x-13)+(6x^4-x^3+8x+27)`

We can get rid of the parenthesis and add like terms and simplify.

Putting answer in standard form means to arrange the terms in descending powers

So, we have:

`(-x^3+26x^2-7x-13)+(6x^4-x^3+8x+27)\\=-x^3+26x^2-7x-13+6x^4-x^3+8x+27\\=6x^4-2x^3+26x^2+x+14`
