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

Answer:

x= -2-√11. or. x= -2 + √11

Step-by-step explanation:

solving quadratic equation by completing the square

x^2+4x-7=0

x^2+4x=7

x^2+4x + (4/2)^2=7 + (4/2)^2 ( adding (1/2 coefficient of x)^2 on both sides

x^2+4x + 4=7 + 4

x^2+4x + 4=11. factorize(x^2+4x + 4) into (x + 2)^2

(x + 2)^2=11

√(x + 2)^2= + - √11

x + 2 = + - √11

there are two different solution .

x + 2 = -√11. or x + 2 = + √11.

x= -2-√11. or. x= -2 + √11.
