Hey asilvester635.
Setting y = 0 means that you are finding the solutions of when the function crosses the x-axis.
This is also known as finding the roots of the equation where f(x) = -x^2 + 3x = 0.
Finding roots to equations has many purposes.

Start by factorizing the equation into (x-a)(x-b) = 0 and then use the fact that x = a and x = b are solutions to this equation since at least one term has to be 0 in order for the LHS to be zero.
