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