What is the improved quadratic formula to solve quadratic equations ?
There is only one quadratic formula, that is
For a general solution of
Now, you can factorize.
This could refer to...
One of the nuisances when using the quadratic formula is that often the square root can be simplified, involving at least one more step than necessary. If the middle coefficient is even, then we can avoid this by using an alternative formulation of the quadratic formula.
#ax^2+2dx+c = 0#
The roots are given by the formula:
#x = -d/a+-sqrt(d^2-ac)/a#
