Question

UpStudy AI · Accepted Answer

1. Write the expression:
   $$
   \left(-5x^2 + x - 6\right) + \left(5x^2 + 2x\right)
   $$

2. Remove the parentheses:
   $$
   -5x^2 + x - 6 + 5x^2 + 2x
   $$

3. Group like terms. For the $$x^2$$ terms:
   $$
   -5x^2 + 5x^2 = 0
   $$
   For the $$x$$ terms:
   $$
   x + 2x = 3x
   $$
   The constant term is $$-6$$.

4. Write the simplified expression:
   $$
   3x - 6
   $$
The simplified expression is $$3x - 6$$.
