Question

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

(x2 – 3x) + (–2x2 + 5x – 3)

Vocaloid · Answer

First distribute the positive sign between the parentheses

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

Combine like terms. Notice how you can combine x ^2 - x^2 to get - x^2. Repeat with the x terms and the constant.

Finally, rewrite in standard form, making sure the terms are in order from highest to lowest exponent.

Attention ! x^2 -2x^2 = -x^2 there up missed the 2 from x^2
