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
x = 2 or x = 2/5
This quadratic equation has no solutions because the discriminant is less than zero.
3x2+14x+8 = 0 x = -2/3 or x = -4

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
Y
X2+11x+11 = 7x+9 X2+11x-7x+11-9 = 0 x2+4x+2 = 0 Solve as a quadratic equation by using the quadratic equation formula or by completing the square: x = -2 + or - the square root of 2
