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)

_________________

       2a            

 

 

 

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.

No..... you are converting the equation to an equation with the leading coefficient  a= 1 to use this 'new'  formula....   just as I said,
