Answer:
[tex]-x^2+2x-3[/tex]
Step-by-step explanation:
The given polynomial expression is
[tex](x^2-3x)+(-2x^2+5x-3)[/tex]
We regroup the terms in the polynomial to obtain;
[tex]x^2-2x^2-3x+5x-3[/tex]
We combine like terms to get;
[tex]-x^2+2x-3[/tex]
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 [tex]-x^2+2x-3[/tex]
