Question

Find all the zeros of the function. When there is an extended list of possible rational zeros, use a graphing utility to graph the function in order to discard any rational zeros that are obviously not zeros of the function. (Enter your answers as a comma-separated list.)
f(x) = 9x3 − 30x2 + 37x − 26

x =

Answer 1

If X= 3
How the is the perimeter of the rectangle 2(6X) + 2(W)=?

Answer 2

9x^3 - 30x^2 + 37x - 26 = 0
A little poking around with synthetic division show that

f(x) = (x-2)(9x^2-12x+13)

So, the only real root is x=2
