Explicación paso a paso:
Dado que :
Área del rectángulo, A = largo * ancho
Dimensión = 3x - 1; x + 2
Área = (3x - 1) * (x + 2)
Área = 3x² + 6x - x - 2
Área = 3x² + 5x - 2

Assume the parabola is placed on a graph where the x-axis is the top of the dish.
The vertex is then at (0,-30) The x-intercepts or zeros are at (-30,0) and (30,0)
The equation of such parabola would be:
Plug in vertex to find value of 'a'
Now find the focus given that
