Gisele solved the quadratic equation x2 + 5x - 6 = 0 by factoring.
Her work is shown below.
Step 1: 22 +52 - 6 = 0
Step 2: (x + 2)(x + 3) = 0
Step 3: 2+2 = 0, 2+3 = 0
Step 4: E= -2 or 2= -3
Step 5: {-2, -3}
Gisele plugged her solutions into the original equation, and found that they did not work.
In which step did she first make a mistake?
