ERROR ANALYSIS Describe and correct the error in finding a reference angle O' for 0 = 650°.

O is coterminal with 290°, whose
terminal side lies in Quadrant IV.
So, 0' = 290° - 270º = 20°.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
