Consider the definite integral. (10x - 1) ex-x dx Let u = 5x2 - x. Use the substitution method to rewrite the function in the integrand, (10x - 1) esx-x, in terms of u. integrand in terms of u: (1 + 1+ 20u e" du IncorrectEvaluate the indefinite integral. (Use symbolic notation and fractions where needed. Use C for the arbitrary constant. Absorb into C as much as possible.) x (4x + 9) dx = (4x + 9)7 7 + C Incorrect
