Given:  <span>y = x^2 + 6x - 5.  Then a = 1, b = 6 and c = -5.

The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.

Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:

y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14

Then the vertex is (-3, -14).</span>

dedylja [7]
Hello,

You can begin by putting the given zeros into factored form.
f(x) = (x + 2)(x - 5)(x - 6) 

Then, you can simplify the equation into standard form.
f(x) = x³ - 9x² + 8x + 60

Your final answer, in standard form, is f(x) = x³ - 9x² + 8x + 60.
