Answer:
1 unique solution (or 2 equal roots)
Step-by-step explanation:
The given quadratic equation as:
f(x)=ax² + bx + c
Given that the leading coefficient which is a is positive and also, the y-coordinate of vertex of the shape of parabola representing the following quadratic equation is 0.
The shape of parabola representing the equation is shown in the image below.
Such quadratic equations has only 1 unique solution (or 2 equal roots).
