900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8
The quadratic formula is...

your a will be in front of your x^2, b in front of your x, and c will be the number without an x. Plug those into the equation and you'll get two answers. That will be it
Hopefully this helps, and sorry I didn't do 8 I'm limited on time
