y = –x4 – 6x3 + 6x2 – 6x + 5
y = – x 4 – 6x 3 + 6x 2 – 6x + 5
y = x4 + 6x3 – 6x2 + 6x – 5
y = x 4 + 6x 3 – 6x 2 + 6x – 5
y = x4 – 6x3 + 5x2 – 6x + 6
y = x 4 – 6x 3 + 5x 2 – 6x + 6
y = x4 – 6x3 + 6x2 – 6x + 5
x = 5 and x = 1

y = x4 + 6x3 – 6x2 + 6x – 5
y = x 4 + 6x 3 – 6x 2 + 6x – 5
y = x4 – 6x3 + 5x2 – 6x + 6
y = x 4 – 6x 3 + 5x 2 – 6x + 6
y = x4 – 6x3 + 6x2 – 6x + 5
y = (x - 5)(x - 1)(x^2 + x + 1)
