Factor the following:
a^2 - a - 90
The factors of -90 that sum to -1 are 9 and -10. So, a^2 - a - 90 = (a + 9) (a - 10):
Answer:  (a + 9) (a - 10)

Plot the vertex, focus, and directrix for the parabola represented by this equation. X=-1/12(y-2)^2+1
alukav5142 [94]

The vertex of the parabola is (1, 2), focus of the parabola is  (-2, 2), and directrix x = 4.

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have a parabola equation:

\rm x = -\dfrac{1}{12}(y-2)^2+1

The standard form of the parabola:

\rm x = \dfrac{1}{4(f-h)}(y-k)^2+h

(h, k) is the vertex of the parabola and (f, k) is the focus.

\rm x = \dfrac{1}{4(-2-1)}(y-2)^2+1

h = 1, k =2, and f = -2

The directrix is x = 4

Thus, the vertex of the parabola is (1, 2), focus (-2, 2), and directrix x = 4.
