Answer:

x = -1

x = 3

Step-by-step explanation:

\sf x^2 - 2x = 3

Add 1 to both sides:

\sf \implies x^2 - 2x+1 = 3+1

Factor the left side:

\sf \implies (x-1)^2 = 4

Square root both sides:

\sf \implies x-1 = \pm2

Therefore:

\sf \implies x-1=-2 \implies x=-1

\sf \implies x-1=2 \implies x=3

xenn [34]

320 portions of waffles can be made with one container.
