Read this article in New York Times about the discovery of a new and much simpler method of solving quadratic equations !!
\(x = -B/2 +or-sqrt(B^2/4 - C)\)
Here is the new formula for solving quadratic equations. Somebody skilled in LaTex can re-write it with + or - on top of each other.
I think this is overrated....I will bet this only works when the leading x^2 coefficient is 1
here is the standard quadratic formula:
-b +- sqrt (b^2 - 4ac)
when a = 1 this becomes: -b/2 +- sqrt (b^2/4 - c) the same 'majic' formula !!!
SO this is just the quadratic formula with a = 1 ....nothing new here folks, move along !
NO! it works for ALL quadratic equations! ; Example: 4x^2 - 20x + 16 =0. You eliminate the coefficient of A by dividing the whole equation by it. So it becomes: x^2 - 5x + 4 =0. Then use the new formula to get: x=1 and x=4.
