Question
$$\left(x^{2}-3\right)-\left(-3 x^{2}+5\right)$$Which of the following expressions is equivalent to the one above?\begin{equation}\begin{array}{l}{\text { A) } 4 x^{2}-8} \\ {\text { B) } 4 x^{2}-2} \\ {\text { C) }-2 x^{2}-8} \\ {\text { D) }-2 x^{2}-2}\end{array}\end{equation}
Step 1
Since there is no coefficient or sign in front of the parentheses, the expression remains the same when we remove the parentheses. So, we have $x^{2}-3$. Show more…
