Answer 1

What is the sum of the given polynomials in standard form?

(x2 – 3x) + (–2x2 + 5x – 3)

–3x2 + 8x – 3

–x2 – 2x – 3

3x2 – 8x + 3

–x2 + 2x – 3

D is the answer

Explanation:

Answer 2

D. -x2 + 2x -3

Explanation:

the first step is we open all the brackets then it will be :

x2 - 3x - 2x2 + 5x - 3

= x2 - 2x2 - 3x + 5x - 3

= -x2 + 2x -3
