Bill and jenna are solving the quadratic equation x^2 0 x = 12.
bill solved this way
x^2 0 x = 12
x(x 0 1) = 12
x = 12 or 13
jenna solved this way
x^2 0 x = 12
x^2 0 x 0 12 = 0
(x 0 4)(x + 3) = 0
x = 4 or x = 03
which student is correct?
what error did the other student make when solving?

Jenna is correct. Bill made mistake in his first step, he did not write the equation in general form of quadratic equation.

Step-by-step explanation:

The given equation is
