Question

If g(x)= x squared- x find the value of g(3b)

Answer 1

If:

$g(x) = x^2-x$

find g(3b). In this problem, you'd literally plug the 3b into the equation. Let's do that:

$g(3b) = (3b)^2-3b$

$g(3b) = 9b^2-3b$

We can further simplify this by pulling out a 3 and a "b":

$g(3b) = 3b(3b-1)$

So, your answer is g(3b) = 3b(b-1).
