Question

check whether X + 1 is a factor of 54 power 3 + X 2 - 5 x -1 ?​

Answer 1

Answer:

Thus x+1 can not be factor of 54³+x²-5x -1

Step-by-step explanation:

Let p(x)= 54³+x²-5x -1

if x+1 is factor of the putting

x+1=0

x=-1

Then p(-1) should be =0

But  P(-1)= 54³+(-1)²-5(-1)-1

=54³+1+5-1

=54³+5

54 and 5 both are positive numbers  so p(-1) can not be zero  

Thus x+1 can not be factor of 54³+x²-5x -1
