2. -7x - 8x
3. -7x2 + 8x
4. 7x + 8x
3 answers
3. -7x2 + 8x
explain
When we distribute the negative sign to the expressions inside the parentheses, it becomes:
-1 * 7x = -7x
-1 * (-8) = 8
So, we get:
-7x + 8x
Which simplifies to:
-7x2 + 8x
Therefore, the correct answer is option 3, -7x2 + 8x.
-1 * 7x = -7x
-1 * (-8) = 8
So, we get:
-7x + 8x
Which simplifies to:
-7x2 + 8x
Therefore, the correct answer is option 3, -7x2 + 8x.
