Question
Explain the error below.Subtract $\left(2 d^{2}-d-3\right)$ from $\left(d^{2}-9\right):$$$\left(2 d^{2}-d-3\right)=\left(d^{2}-9\right)=d^{2}-d+6$$
Step 1
We are asked to subtract $\left(2 d^{2}-d-3\right)$ from $\left(d^{2}-9\right)$. This means we need to subtract each term in $\left(2 d^{2}-d-3\right)$ from $\left(d^{2}-9\right)$. Show more…
