x2+4x+4 = 0
(x+2)(x+2) = 0
x = -2 and also x = -2
When the solutions to a quadratic equation are identical this means that both values are at the turning point or vertex of the parabola just on the x axis.
d>=0,then roots of quadratic equation are real
if D<0,then roots are imaginary
(6, 0) and (0, 8)
x=3 y=2 z=6
4x + 3y = 6y 4x = 3y 4/3 x = y The slope is 4/3 and the y intercept is 0.
None because the discriminant of this quadratic equation is less than zero.
