2 consecutive positive integers....x and x + 1
" the product " means multiply and " the sum " means add
x(x + 1) = x + (x + 1) + 1
x^2 + x = 2x + 2
x^2 - 2x + x - 2 = 0
x^2 - x - 2 = 0
(x + 1)(x - 2) = 0
x + 1 = 0
x = -1......not this one because it is negative
x - 2 = 0
x = 2
x + 1 = 2 + 1 = 3
so ur numbers are : 2 and 3 <==

First let

, so that

to write the integral as

Now recall that

, so substituting

should do the trick. The integral then becomes
I think 30c+3d would be the correct answer.
