Answer:
-3s² + 16s - 7
Step-by-step explanation:
Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).
First, distribute -3s to s and -10, and 7 to -2s and -1:
-3s(s - 10) = -3s² + 30s
7(-2s - 1) = -14s - 7
Next, combine like terms:
-3s² + 30s - 14s - 7
-3s² + (30s - 14s) - 7
-3s² + 16s - 7
-3s² + 16s - 7 is your answer.
