Subtract $2p^4\text{ from }-7p^4$

Step-by-Step Solution

Answer

On subtracting $2p^4\text{ from }-7p^4$, we get $-9p^4$

Step 1. Given information

$\begin{array}{l}\text{We have to subtract }2p^4\text{ from }-7p^4.\\ i.e\text{ We have to solve }-7p^4-2p^4.\end{array}$

Step 2. Subtract

$\begin{array}{l}\Rightarrow -7p^4-2p^4\\ =\left(-7-2\right)p^4\left[\text{Combine the like terms and simplify}\right]\\ =-9p^4\end{array}$
