Question

if X + 1 is a factor of polynomial 2 x ^2 + k x then the value of k is . THOSE WHO KNOWS ANSWER THEY ONLY GIVES, ANSWER. AND WHO ARE JUST ANSWERING FOR GETTING POINT AND ANSWER SOME MISCHIEVOUS ANSWER I WILL REPORT ANSWER. THANK YOU .

Answer 1

Hii friend,


(X+1) is a factor of the given polynomial.

Therefore,


(X+1) = 0


X = -1


P(X) => 2X²+KX


P(-1) => 2 × (-1)² + K × -1

=> 2 × 1 - K


=> 2 - K = 0


=> K = 2



HOPE IT WILL HELP YOU...... ;-)
