Step-by-step explanation:
Answer:
6+y
-23
Step-by-step explanation:
Just write it out.
Let u = 5x+1. Then du = 5·dx, and your integral is

Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15
