Question

Find the value of k if (x-1) is factor of p(x) in each of following case.

i] p(x)=x2+x+k
ii] kx2-3x+k

HELP PLEASE

​

Answer 1

Answer:

i)-2 ii)3/2

Step-by-step explanation:

In each case x-1=0

= x=-2

i) p(x)=x^2+x+k

p(1)=1+1+k=0

2+k=0

k = -2

ii) p(x)=kx^2-3x+k

p(1)=k^(1)-3(1)+k=0

k-3+k=0

2k-3=0

k=3/2
