UpStudy AI · Accepted Answer

To subtract the given polynomials:

$$
\left(\frac{3}{8} s^{8}-\frac{3}{4} s^{7}\right)-\left(\frac{1}{3} s^{8}+\frac{1}{5} s^{7}\right)
$$

First, distribute the subtraction:

$$
\frac{3}{8} s^{8} - \frac{3}{4} s^{7} - \frac{1}{3} s^{8} - \frac{1}{5} s^{7}
$$

Next, combine like terms:

$$
\left(\frac{3}{8} - \frac{1}{3}\right) s^{8} + \left(-\frac{3}{4} - \frac{1}{5}\right) s^{7}
$$

Calculate each coefficient:

1. For $$s^{8}$$:

$$
\frac{3}{8} - \frac{1}{3} = \frac{9}{24} - \frac{8}{24} = \frac{1}{24}
$$

2. For $$s^{7}$$:

$$
-\frac{3}{4} - \frac{1}{5} = -\frac{15}{20} - \frac{4}{20} = -\frac{19}{20}
$$

Putting it all together:

$$
\frac{1}{24} s^{8} - \frac{19}{20} s^{7}
$$

**Final Answer:**

$$
\frac{1}{24}\, s^{8} - \frac{19}{20}\, s^{7}
$$
$$ \frac{1}{24} s^{8} - \frac{19}{20} s^{7} $$
