Answer:
x^3 -x^2 + 25x - 25
Step-by-step explanation:
x = 1
x = 5i
x = -5i
(x - 1)(x - 5i)(x + 5i)
Multiply
(x - 1)(x^2 + 5ix - 5ix + 25) *Remember that i multiplied by i equals negative and in this situation, one of the variables was already negative, so negative multiplied by negative is positive*
(x - 1)(x^2 + 25)
Multiply again
x^3 + 25x -1x^2 - 25
x^3 -x^2 + 25x - 25
