Find K if x + 1 is a factor of P(x) = Kx^2-x+2

wlad13 [49]

Answer:

$K=-3$

Step-by-step explanation:

According to the Factor Theorem, a binomial (x - a) is a factor of a polynomial P(x) if and only if P(a) = 0.

We have the polynomial:

$P(x)=Kx^2-x+2$

And we want to find the value of K such that (x + 1) is a factor.

We can rewrite our factor as (x - (-1)). Thus, a = -1.

Then in orer for (x + 1) to be a factor, P(-1) must equal 0. Hence:

$P(-1)=K(-1)^2-(-1)+2=0$

Simplify:

$K+1+2=0$

Solve for K. Hence:

$K=-3$
