1) 2+ 13x^2- 2( X^2 + 4x^3)

= 2+ 13x^2- 2x^2- 8x^3

= -8x^3+11x^2+2

2 + 13x^2 - 2(x^2+4x^3)

Distribute the -2 to the parenthesis you will end up with

2 + 13x^2 - 2x^2 - 8x^3

now combine like terms

2 + 11x^2 - 8x^3

put the numbers in descending order (the ones with the highest exponents go first 

-8x^3 + 11x^2 + 2

That's the answer
