+476 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?
+9466 Hmmm...how about...
Solve for x.
ax2 + 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...
+2440 I was going to ask the exact same question! I almost typed it out and realized that someone beat me to it. :(
+476 It's a basic quadratic function.
step1: ax2+bx+c = 0
It takes a while, but you eventually get to the quadratic formula, x=(-b ± sqrt(b2-4ac)/2a
Also, is there a plus/minus button? I just copied the symbol I used off Google.
+2440 Here's a system for you:
\(-4x+y-2z=-14\)
\(8x-2y+4z=7\)\(2x-4y+z=3\)
