13. When you have a negative sign before the parenthesis, the signs change in inside!
So, the answer is -14x^4+5x^3+6, after the calculations!
Use the same method for 14!

13. (8x3−6x4+3)−(3x3−3+8x4)=8x3−6x4+3−3x3+3−8x4=−14x4+5x3+3+3=−14x4+5x3+6.
Remember! When you have a negative sign before the parenthesis, the signs change in inside!
