%281%2F6%29x%5E2-%281%2F2%29x%5E3%2Bx%5E2-%281%2F4%29x%5E3%2B17 Start with the given expression.


%28-%281%2F2%29x%5E3-%281%2F4%29x%5E3%29%2B%28%281%2F6%29x%5E2%2Bx%5E2%29%2B17 Rearrange and group like terms (ie the terms that have the same exponent)


%28-%282%2F4%29x%5E3-%281%2F4%29x%5E3%29%2B%28%281%2F6%29x%5E2%2Bx%5E2%29%2B17 Multiply -1%2F2 (the coefficient of the first term) by 2%2F2


%28-%282%2F4%29x%5E3-%281%2F4%29x%5E3%29%2B%28%281%2F6%29x%5E2%2B%286%2F6%29x%5E2%29%2B17 Multiply 1 (the coefficient of the fourth term) by 6%2F6


-%283%2F4%29x%5E3%2B%287%2F6%29x%5E2%2B17 Combine like terms by combining the fractional coefficients.
