Simplify. (3x5+3x2−4x3+x−6)−(x3+4x4+2x2−10x) Enter your answer, in standard form, in the box.

All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.

This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x

Then combine like terms and line all the values in order from greatest exponent value to least to get 
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6

Hope this helped :)
