x2 - 4x + 1 = 0
p=4
q=1
x = -p/2 +- sqrt((p/2)2 - q)
x = -4/2 +- sqrt((4/2)2 - 1)
x = -2 +- sqrt(4-1)
x1= -2 + sqrt(3)
x2= -2 - sqrt(3)
Please do not remove this question from Inappropriate or split any alts from it. Thanks!
It cannot be solved because the discriminant of the quadratic equation is less than zero
This quadratic equation has no solutions because the discriminant is less than zero.
x = 2 or x = 2/5
3x2+14x+8 = 0 x = -2/3 or x = -4

100 equales
25x (square) plus 40 plus 15 equals 680.
If: x^2 +18x = 29 Then completing the square: (x+9)^2 -81 = 29 or (x+9)^2 = 110
