Question 781625
4x^2 + 10x - 16 = 0
x^2 + 5x = 8
c = (b/2a)^2 = (5/2)^2
c = 25/4
------
x^2 + 5x + 25/4 = 8 + 25/4 = 57/4
(x + 5/2)^2 = 57/4
{{{x + 5/2 = sqrt(57)/2}}}
{{{x + 5/2 = -sqrt(57)/2}}}
------------
There is no DNE for quadratics.
There are always 2 solutions, tho sometimes they're equal.
