his total bill would be 698.75
Step-by-step explanation

Answer:
x = 2 and x = -2
Step-by-step explanation:
The quadratic formula of a quadratic of the form ax² + bx + c is:
x =
or x = ![\frac{-b-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
Here, our equation is: 3x² - 18 = -6. Let's move all the terms to one side:
3x² - 12 = 0
a = 3 and c = -12. Notice that since there's no x term, b = 0.
Plug these into the quadratic formula:
x =
or
x = ![\frac{0-\sqrt{0^2-4*3*(-12)} }{2*3}=\frac{-\sqrt{144} }{6}=-12/6=-2](https://tex.z-dn.net/?f=%5Cfrac%7B0-%5Csqrt%7B0%5E2-4%2A3%2A%28-12%29%7D%20%7D%7B2%2A3%7D%3D%5Cfrac%7B-%5Csqrt%7B144%7D%20%7D%7B6%7D%3D-12%2F6%3D-2)
So, x = 2 and x = -2.
