So, plug in what you're given and solve
 x is -2
(3x) * 9 
(3 (-2)) * 9
-6 * 9
-54

then 
27(-2)
-54
For the first it's the same

for the second
x is 0
(3x) * 9
(3 (0)) * 9
0 * 9
0

27x
27(0)
0
For the second it's the same

x is 4
(3x) * 9 
(3(4)) * 9
12 * 9
108

27x 
27(4)
108

The given expressions are equivalent. This was proved in the diagram.

Let f(x) = x^2 - 11x - 60.<br> Solve for f(x) using factoring.
Alona [7]
F(x) = X^2 - 11x - 60
Two terms that multiply to -60 and add to -11 so...
F(x) = (X - 15) (x + 4)
Your x-intercepts would be 15 and -4.
