Question

Find the value of k if (x-2) is factor of p(x) and p(x)= x square + x + k

Answer 1

Answer:

if x-2 is factor so x = 2

put the value of x in eq.

p(x) = (2)^2+2+k= 6+k

hence k = -6

Answer 2

Answer:

k = -6

Step-by-step explanation:

x-2=0

x = 2

p(2) = 2² + 2 + k

0 = 4+2+k

0= 6+k

k = -6
