Guys, it comes out to about .70472 or about -1.419. Just plug it in to a graphing calculator and find what X equals when y is 0. |
Math, it burns!

Easy:
1: Turn it into an ax^2+bx+c=0 format
7x^2+5x-6
2: If this were a graph, you need to find what X equals when Y=0. To do that, use the quadratic formula: "negative b plus-or-minus the square root of b squared minus 4ac over 2a" (I cannot for the life of me figure out the right html format to write that as an equation)
3: Do the math.
X=.635 and X=-1.350
Plug them in, and you'll see they fit (approximately; they had to be rounded).
Thank you!

X= -b+ ll b^2-4ac
2a
(The double line is the square root sign, and the underline is a fraction)
Or something like that.

Or you can use the Quadratic Equation. Don't forget the song! "X equals negative b. Plus or minus the square root. b squared minus 4 a c. All over 2 a." (Sung like Pop Goes the Weasel) |
A bunch from "The Boiling Rock." Don't click if you don't want to be spoiled.

I know I aced my final algebra exam, but when the heck did this become the "Discuss Advanced Algebra Motivational Posters on DA" thread?? Because I think someone needs to change the sign, and I need to start steering clear of it... |

Aaah, the algebra crap is good, but that's old. What about parametric equations?

LEAVE PARAMETRIC EQUATIONS ALONE!!!!
