When finding the tangent slope function for the quadratic function f(x) = 3x^2 - 5x + 2, what would be the expression involved in the second last line if we use (x + h) as a second x value?
Options:
A. (x + h)^2 - 5(x + h) + 2
B. 3(x + h)^2 - 5(x + h) + 2
C. 3(x + h)^2 - 5(x + h)
D. (x + h)^2 - 5(x + h)
