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

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
