Question

If x+1 is a factor of the polynomial 2x² + kx, then the value of 'k' is___________ a) -3 b) 4 c) 2 d) -2 ​

Answer 1

when xt1 is a foctor of polynomial 2x^2+kx then the valu of k is 2 option c is wright ans

Answer 2

Answer:

d)-2

Step-by-step explanation:

Let,g(x)=x+1=0

=)x=-1

P(x)=2x²+kx=0

putting,

P(-1)=2×(-1)²+k×(-1)

=)2-k=0

=)k=-2
