Post a question that is algebra II level, I need a question to work on

by the way, how do you enter an uppercase sigma on the calculator to calculate sums?

Hmmm...how about...

Solve for x.

ax^{2} + bx + c = 0

You will need to "complete the square" to get the answer.

I think this is probably algebra II level, but I'm not sure.

Or maybe you've done this already...

I was going to ask the exact same question! I almost typed it out and realized that someone beat me to it. :(

It's a basic quadratic function.

step1: ax^{2}+bx+c = 0

It takes a while, but you eventually get to the quadratic formula, x=(-b ± sqrt(b^{2}-4ac)/2a

Also, is there a plus/minus button? I just copied the symbol I used off Google.

Here's a system for you:

\(-4x+y-2z=-14\)

\(8x-2y+4z=7\)\(2x-4y+z=3\)
