Gisele Solved the quadratic equation X^2 + 5x - 6 = 0 by factoring her work is shown below:

Step 1: X^2 + 5x - 6 = 0
Step 2: (x + 2)(x + 3) = 0
Step 3: x + 2 = 0, x + 3 = 0
Step 4: x = -2 or x = -3
Step 5: -2, -3

Gisele plugged her solution into the original equation and found that they did not work. In which step did she first make a mistake?
A. Step 1
B. Step 2
C. Step 3
D. Step 4

Final answer:

Gisele made a mistake in Step 2 when factoring the quadratic equation.

Step-by-step explanation:

Gisele made a mistake in Step 2 when she factored the expression incorrectly. The correct factored form of x^2 + 5x - 6 = 0 should be (x + 6)(x - 1) = 0. Therefore, her subsequent steps and solutions are also incorrect.
