Simplify (-7x-5x^4+5)-(-7x^4-5-9x)

Problem

(−7*x−5*x4+5)−(−7*x4−5−9*x)

Solution

1. Distribute the negative sign to each term inside the second set of parentheses.

(−7*x−5*x4+5)+7*x4+5+9*x

2. Remove the parentheses and group the terms by their degree.

−5*x4+7*x4−7*x+9*x+5+5

3. Combine the like terms for the x4 power.

2*x4−7*x+9*x+5+5

4. Combine the like terms for the x power.

2*x4+2*x+5+5

5. Combine the constant terms to reach the final simplified form.

2*x4+2*x+10

Final Answer

(−7*x−5*x4+5)−(−7*x4−5−9*x)=2*x4+2*x+10
