Answer 4

For the first one, since the sign in front of the parenthesis is a plus sign, you can just drop the parenthesis and add like terms. If the terms share the same variable to the same power, just add their coefficients. So for example, if you have 5x^5 + 4x^3 - 2x^3 + x^5. Well, you take all the ones with x^5, since they match, and add their coefficients. So you would have 5x^5 + x^5 = 6x^5 and 4x^3 - 2x^3 - 2x^3.

Just apply that to these problems.

For number 2 its the same thing, but the negative on the outside of the parenthesis forces you to change the signs of everything inside of theparenthesis:

\[-(4x^{2} - 15x + 7)= -1*(4x^{2} - 15x + 7)\]
