Question

If one zero of the polynomial p(x)=x2-x-(2+2k) is -4 then value of k is ---

​

Answer 1

Answer:

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

p (-4)= (-4)^2-(-4)-(2+2k)=0

= 16+4-2-2k=0

=18-2k=0

18= 2k

k= 9

Answer 2

Step-by-step explanation:

If x2 means 2x , then answer value of k is zero , otherwise , value of k is 9
