Mathematics

a = 3, b = 5

Step-by-step explanation:

We are given the following expression:

$\frac{3}{x} +\frac{5}{x^2}$ which we are supposed to simplify and tell the values of and that complete the sum by justifying it.

So to solve this expression, we will take the LCM of both the fractions and write it in the form of a single fraction.

$\frac{3}{x} +\frac{5}{x^2}$

$\frac{3x+5}{x^2}$

So this is the simplified expression in the form $\frac{ax+b}{x^2}$ where a = 3 and b=5 .
