I'm assuming the 0s are negative signs. 

Anyway, Jenna did the correct way to solve it. Bill didn't solve the quadratic equation correctly because he didn't proceed to solving for the zeros of the equation - which Jenna did.

Answer:

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

x^2-x=12

The general form of a quadratic equation is

Ax^2+Bx+C=0

The given equation can be written as

x^2-x-12=0

x^2-4x+3x-12=0

x(x-4)+3(x-4)=0

(x-4)(x+3)=0

x=4,-3

Therefore, Jenna is correct.

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