Answer:

Step 3.

Step-by-step explanation:

When you distribute this [tex](-3)(x-5)[/tex],

you should get [tex]-3x+(-3)(-5)[/tex].

However, [tex]-3*-5=15[/tex] and not [tex]-15[/tex] because of the double negative.

Step three contains the error because when expanding -3*-5, the answer is +15, not -15
