Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$C=(-16,-4),(16,4),(-9,-3),(9,3),(9,3),(-4,2),(4,-2)$$

Answer

C=-16,-4,16,4,-9,-3,9,3,2,-2

Solution


Remove parentheses.
\[C=-4,4,-9,-3,9,3,9,3,-4,4,\pm 16,\pm 2\]
Already solved. No work needed.
\[C=-4,4,-9,-3,9,3,9,3,-4,4,\pm 16,\pm 2\]
Therefore,
\(C=\pm 16,\pm 4,\pm 9,\pm 3,\pm 2\)
