Answer
$=\dfrac{-5y-15z-25xz}{x}$
Work Step by Step
Divide the divisor to each term of the dividend to have:
$=\dfrac{25xy^2}{-5x^2y}+\dfrac{75xyz}{-5x^2y}+\dfrac{125x^2yz}{-5x^2y}$
$=-\dfrac{5y}{x}-\dfrac{15z}{x}-25z$
$=\dfrac{-5y-15z}{x}-25z$
$=-\dfrac{5y-15z}{x} - \dfrac{25xz}{x}$
$=\dfrac{-5y-15z-25xz}{x}$
