Question

What is the sum of the given polynomials in standard form?
(x2 – 3x) + (–2x2 + 5x – 3)

Answer 1

`-x^2+2x-3`

Explanation:

The given polynomial expression is

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

We regroup the terms in the polynomial to obtain;

`x^2-2x^2-3x+5x-3`

We combine like terms to get;

`-x^2+2x-3`

When we arrange the terms in the polynomial in descending powers of x, then we say it is in standard form.

The simplified polynomial in standard form is
`-x^2+2x-3`

Answer 2

Combine like terms. -x2 +2x -3 is the answer.
