Oh wow thanks!
OpenStudy (mathmale):
1. Since the parentheses around 5x^3 - x + 14 are not needed, you can eliminate them: 5x^3 - x + 14 2. The negative sign in front of (3x^2 - 9x +4) requires that you change the sign of all 3 terms within these parentheses. -(3x^2) becomes -3x^2. And so on. Write the 2nd and 3rd terms, please.
