Question

Evaluate the integral. (assume a ≠
b. remember to use absolute values where appropriate. use c for the constant of integration.) 3 (x + a)(x +
b.dx

Answer 1

I am assuming there's a right parenthesis after the b.

3(x + a)(x + b)

=  3(x^2 + bx + ax + ab)
= 3x^2 + 3bx +  3ax + 3ab

Integral  = x^3 + 3bx^2/2 + 3ax^2 / 2 + 3abx  + c   Answer
