Answer 1

Answer:

10x^3+13x^2-15x-67

Step-by-step explanation:

First you distribute- 10x^3+25x^2-40-12x^2-15x-27

                      you distribute the 5 through then the negative 3 through

Then you combine like terms

        10x^3+13x^2-15x-67

Then that is just your answer after you add the ones with the squared together and the ones with no variables together
