Find $a+b+c$ if the graph of the equation $y=ax^2+bx+c$ is a parabola with vertex $(5,3)$, vertical axis of symmetry, and contains the point $(2,0)$.

Step-by-step explanation:

Given:

The equation of the parabola with vertical axis of symmetry is given as:

Vertex of the parabola is,

Point on a parabola is (2,0).

The co-ordinate of the vertex is given as:

Now, plug in the point (2,0) in the parabolic equation. This gives,

Now, as vertex lies on the parabola, plug in (5,3) in the parabolic equation. This gives,

So,

Therefore, the sum of is:
