#### Answer

$\dfrac{4x-5}{3x^{2}}-\dfrac{2x+5}{3x^{2}}=\dfrac{2(x-5)}{3x^{2}}$

#### Work Step by Step

$\dfrac{4x-5}{3x^{2}}-\dfrac{2x+5}{3x^{2}}$
Evaluate the substraction:
$\dfrac{4x-5}{3x^{2}}-\dfrac{2x+5}{3x^{2}}=\dfrac{(4x-5)-(2x+5)}{3x^{2}}=...$
$...=\dfrac{4x-5-2x-5}{3x^{2}}=\dfrac{2x-10}{3x^{2}}=...$
Take out common factor $2$ from the numerator to provide a more simplified answer:
$...=\dfrac{2(x-5)}{3x^{2}}$
