Answer 1

Step-by-step explanation:

Given:

$\frac{7}{2}x {}^{2} - \frac{1}{2}x {}^{2} + \frac{5}{3} - \frac{3}{2}x {}^{3} + \frac{7}{4}x {}^{2} - \frac{1}{4}x - 4 \\ = - \frac{3}{2}x {}^{3} + ( \frac{7}{2} + \frac{7}{4} - \frac{1}{2})x {}^{2} - \frac{1}{4}x + \frac{5}{3} - 4 \\ = - \frac{3}{2}x {}^{3} + ( \frac{21}{4} - \frac{1}{2})x {}^{2} - \frac{1}{4}x - \frac{7}{3} \\ = - \frac{3}{2}x {}^{3} + \frac{19}{4}x {}^{2} - \frac{1}{4}x - \frac{7}{3}$
