Standard Form conversion

How would I convert this equation to standard form? y = -2 (x - 6)^2 + 8

What is the value of x in the equation 8x^2 - 6x + 1 = 0? I've been stuck on this for half an hour, it just doesn't seem logical to me.

Use the quadratic formula to solve these equations, showing work. (x^2) + 4x - 2 = 0 -6(x^2) + 3x + 2 = 3 -(x^2) +1 = -5(x^2) + 4x 2(x - 3)^

Use the quadratic formula to solve these equations, showing work. Of course, every equation's value of x is independent from the rest.
(x^2) + 4x - 2 = 0
-6(x^2) + 3x + 2 = 3
-(x^2) +1 = -5(x^2) + 4x read more ..

I knew it. I knew that whoever answered this actually answered in binary. Good job. Have a thumbs-up.

Well, if you wouldn't mind helping w/ one of those two-sided ones, that'd be great. Is it done the same way, just using the formula on both sides?

Well, to be fair, that isn't all of it.

But I seriously thought the point of this site was to get help with math homework. Granted, I could (and should) have just asked for you guys to answer one and then applied the steps to the rest.
