Question

Find The value of k, if x - is a
factor of foot Poc) = x to tk​

Answer 1

Answer:

Explanation:

Here, (x−1) is a factor of p(x) that means from Factor theorem,

p(1)=0.

(i)p(x)=x2+x+k

As, p(1) is 0

0=12+1+k⇒k=−2

(ii)p(x)=2x2+kx+2–√

As, p(1) is 0

2+k+2–√=0⇒k=−(2+2–√)

(iii)p(x)=kx2−2–√x+1

As, p(1) is 0

k−2–√+1=0⇒k=2–√−1

(iv)p(x)=kx2−3x+k

As, p(1) is 0

k−3+k=0⇒2k=3

k=32
