Is (x-5) a factor of P(x)=x4 - 3x® – 9x² - 4x? Say YES or NO and explain your answer

No , (x-5) is not a factor

Step-by-step explanation:

x⁴ - 3x³ – 9x² - 4x = (x³ + 2x² + x + 1) (x - 5) + 5

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

the answer is 8/21
