Answer:

Step-by-step explanation:
The factored form of a quadratic is given by:

Where <em>p</em> and <em>q</em> are the zeros, and <em>a</em> is the leading coefficient.
The quadratic relation has zeros of 5 and 6, and it has a y-intercept of 30.
Since the zeros are 5 and 6, <em>p </em>and <em>q</em> are 5 and 6. Thus:

The y-intercept is 30. In other words, when <em>x </em>= 0, <em>f(x)</em> = 30:

Solve for a:

Therefore, our quadratic in factored form is:

To find the standard form, expand:
