Question

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

Answer 1

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

Answer 2

Answer:

$-x^2+2x-3$

Step-by-step 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  $-x^2+2x-3$
