Answer:
x^3 + 2x^2 + x + 3
Step-by-step explanation:
When it says that that the polynomial is subtracted from the value x^3 - x^2+ 3x, that would mean that the answer can be computed from the following format:
(x^3 - x^2+ 3x) - (-3x^2 + 2x - 3)
Use the distributive property for the better, distributing the - to the numbers in parenthesis, to get:
(x^3-x^2+ 3x) + 3x^2 -2x + 3
Now take the parenthesis out of the first polynomial in the equation, as it isn't needed:
x^3 - x^2 + 3x + 3x^2 - 2x + 3
Rearrange and combine like values:
x^3 - x^2 + 3x^2 + 3x -2x + 3 ,
x^3 + 2x^2 + x + 3
