In the following exercises , simplify the expression $(j^{2} - 8 j - 27) - (j^{2} + 2 j - 12)$ .

Short Answer

Expert verified

The simplified expression is $- 10 j - 15$ .

Step by step solution

Step 1. Given Information .

The given expression is $(j^{2} - 8 j - 27) - (j^{2} + 2 j - 12)$ .

Step 2. Simplify the given expression.

Simplify the expression $(j^{2} - 8 j - 27) - (j^{2} + 2 j - 12)$

$\begin{array}{rcl} (j^{2} - 8 j - 27) - (j^{2} + 2 j - 12) & = & j^{2} - 8 j - 27 - j^{2} - 2 j + 12 \\ j^{2} - 8 j - 27 - j^{2} - 2 j + 12 & = & j^{2} - j^{2} - 8 j - 2 j - 27 + 12 \\ j^{2} - j^{2} - 8 j - 2 j - 27 + 12 & = & - 10 j - 15 \end{array}$
