Answer

Final Answer: The simplified expression after multiplying the two rational expressions is $\frac{10}{7}$

Steps

Step 1 ：Given the rational expressions $\frac{x - 3}{x + 5}$ and $\frac{10 x + 50}{7 x - 21}$

Step 2 ：To multiply these expressions, we multiply the numerators together to get the new numerator and the denominators together to get the new denominator.

Step 3 ：The new numerator is $(x - 3) * (10 * x + 50)$

Step 4 ：The new denominator is $(x + 5) * (7 * x - 21)$

Step 5 ：After simplifying the expression, we get $\frac{10}{7}$

Step 6 ：Final Answer: The simplified expression after multiplying the two rational expressions is $\frac{10}{7}$
