Every quadratic equation has two solutions.
If the quadratic expression that's equal to zero is a perfect square,
then the two solutions are equal, and they look like one solution.
Example:
x2 - 6x + 9 = 0
(x - 3)(x - 3) = (x - 3)2 = 0
x = 3
and
x = 3.

Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
No, it must have two answers.
They are the solutions for the reduced quadratic.
b^2 - 4ac, the discriminant will tell you that a quadratic equation may have one real solution( discriminant = 0 ) , two real solutions( discriminant > 0 ), or no real solutions( discriminant < 0 ).
Normally it has two solutions but sometimes the solutions can be the same.
