Consider the polynomial P(x)=x³+kx²+x+6.Find the value of k so that x+1 is a factor of P.

sergiy2304 [10]

Answer:

The value of k will be -4

Step-by-step explanation:

We have given polynomial $P(X)=x^3+kx^2+x+6$

It is given that x+1 is factor of the polynomial

And we have to find the value of k

As x+1 is the factor of polynomial so x+1 = 0 that is x = -1 will be the root of polynomial

So if we put x = -1 in the polynomial then the p(-1) will be zero

So $0=(-1)^3+k(-1)^2-1+6$

$k=-4$

So the value of k will be -4

Ms. Callahan had 250 sheets of paper. She used 6 sheets of paper. She then gave each student 3 sheets of paper.

irina [24]

The answer would be D if it was 250-6-3n. it wouldnt be A or C because 9 isnt anywhere in the problem and it wouldnt be B because she used 6 peices of paper she didnt just give it to her students
