Please help!!!! BRAINLIEST for whoever is correct!! What is the difference of the rational expressions below?
Nostrana [21]

Answer:

<h2>\frac{3x + 25}{5 {x}^{2} }</h2>

Step-by-step explanation:

\frac{x + 5}{ {x}^{2} }  -  \frac{2}{5x}

Write all the numbers above the least common denominator {5x}^{2}

\frac{5(x + 5) - 2x}{5 {x}^{2} }

Distribute 5 through the parentheses

\frac{5x + 25 - 2x}{5 {x}^{2} }

Collect like terms

\frac{3x + 25}{5 {x}^{2} }

Hope this helps...

Good luck on your assignment...

b. self explanatory I guess, my answer pretty much explained it.
