Question

Divide the following: −15d3−50d2−25d5d3=

Answer 1

`\begin{gathered} (-15d^3-50d^2-25d)/(5d^3) \\ \\ common\text{ factor is 5d} \\ (5d(-3d^2-10d-5))/(5d(d^2))=(5d)/(5d)\cdot(-3d^2-10d-5)/(d^2)=1\cdot(-3d^2-10d-5)/(d^2) \\ \\ =(-3d^2-10d-5)/(d^2) \\ \text{Hence} \\ (-15d^3-50d^2-25d)/(5d^3)=(-3d^2-10d-5)/(d^2) \end{gathered}`
