Evaluate the discriminant of 3x2 + 2x + 1 = 0. Tell how many solutions the equation has and whether the solutions are real or imaginary.
A.
two imaginary solutions
B.
one real solution
C.
two real solutions
D.
cannot be determined

3x^2 + 2x + 1 = 0 discriminant = b^2 - 4ac = 2^2 - 4(3)(1) = 4 - 12 = -8 < 0 Therefore, there are two imaginary solutions for the equation 3x^2 + 2x + 1 = 0.

3x^2 + 2x + 1 = 0

discriminant = b^2 - 4ac = 2^2 - 4(3)(1) = 4 - 12 = -8 < 0

Therefore, there are two imaginary solutions for the equation 3x^2 + 2x + 1 = 0.

discriminant = b^2 - 4ac = 2^2 - 4(3)(1) = 4 - 12 = -8 < 0

Therefore, there are two imaginary solutions for the equation 3x^2 + 2x + 1 = 0.

The minimum value of a parabola that opens upward will be its vertex.
A.
True
B.
False
**Weegy:** The vertex of a parabola is the point where the parabola crosses its axis. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the ?U?-shape. [ If the coefficient of the x2 term is negative, the vertex will be the highest point on the graph, the point at the top of the ?U?-shape.
The standard equation of a parabola is
y = ax2 + bx + c.
But the equation for a parabola can also be written in "vertex form":
y = a(x ? h)2 + k ] (More)
