Can anyone help me to understand what the above statement means? I cannot figure it out. I have had Algebra 1, and Geometry 1, and I can't figure it out.
"x" only appears twice in the quadratic equation. It has a power of of 1 and 2. Since, 2 is higher than 1, 2 is the highest power. Also known as "squared"
x only appears once in the quadratic equation? Who said anything about x having a power of 1 and 2? I get it if that statement(s) is true, but where did you get the first part from?

Yeah, it should be: x = -b +/- square root of (b^2 -4ac) over 2a
In a equation like:
x2 + 3x – 4 = 0
This quadratic happens to factor:
x2 + 3x – 4 = (x + 4)(x – 1) = 0
Using a = 1, b = 3, and c = –4
Just fill it in. IF you have a t83 or 84 calculator then there is a way to do this without writing it out. I can help you if you need more help. Computer Science major :wink:
I have the ti84 plus silver edition, it's just at home, 2 states away! It would help I know. I might get you to explain that again when I get home Brock.
I guess when you simplify x = (-b +/- square root of (c^2 - 4ac)) / 2a it becomes ax^2 + bx + c = 0 which is a way to find the roots by factoring, so thats how you get to ax^2 + bx + c = 0, the highest power of an unknown number is a square.
