Question

The quotient obtained when $4m^5-4m^3+4$ is divided by $2m^2$ is

• A. $2m^2+2m$
• B. $2m^2-2m$
• C. $2m^3+2m$
• D. $2m^3-2m$

Answer 1

The correct option is D $2m^3-2m$

The required division is shown below:
$$\begin{array}{c}2m^3-2m\\ 2m^{2}4m^5-4m^3+4\\ \underset{–}{4m^5-}2\\ 0-4m^3+4\\ \underset{–}{-4m^3+}\\ +4\end{array}$$
