Question

22. If x + 2 is a factor of the polynomial 3x2 – kx, then find the value

of k.​

Answer 1

X= -2 is a root of given polynomial,

then, substituting the value of x = - 2 in P(X)

$we \: have \: \\ p(x) = 3 {x}^{2} - kx \\ p( - 2) = 3 \times 4 + 2k \\ 12 + 2k = 0 = > k = \frac{ - 12}{2} = - 6$
