How does the formula -b over 2a work?
The quadratic formula is "[minus b] over 2a, plus or minus the square root of [b squared minus 4ac], over 2a". where the formula for the variable is in the form a(x2) + b(x) + c = 0 By setting the equation into this form, you can use the integer values a, b, and c to find the solution for x, simply by multiplying, taking the square root, and adding. As the equation describes a curve, the two solutions (plus or minus) are the x-intercepts (y=0) of the curve, and the y-intercept (x=0) is at c. * For the shorter form ax2 + 2kx + c where k is an even number, see the related link.
