Question

4. If x+1 is a factor of the polynomial 2x(x+k), then the value of k is:​

Answer 1

Answer:

$x + 1 = 0 \\ x = 1 \\ 2x(x + k) \\ 2 x {}^{2} + k \\ \\ p(1) = 2(1 {}^{2} ) + k \\ 2 + k = 0 \\ k = \frac{0}{2} \\ here \: is \: your \: answer \\ mark \: me \: as \: a \: brainelist$

put 1 in place of x
