Write a ponlynomial funstion in standard form with zeros at -2, 5 and 6

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. 

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
