If x + 1 is a factor of the polynomial 2x2 + kx, then the value of k is. A. -3.

9 янв. 2020 г. · Since x+1 is a factor of the above polynomial, p(−1)=0. ∴2×(−1)2+k(−1)=0 ∴2−k=0 ∴k=2. Was this answer helpful?

6 янв. 2022 г. · 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. Solution: Consider p(x) = 2x² + kx.

The correct Answer is:C. Let p(x)=2x2+kx. Since ,(x+1) is a factor of p(x) then p(-1) =0 ∴ 2(−1)2+k(−1)=0 ⇒ 2−l=0⇒k=2. Hence , the value of k is 2.

17 дек. 2021 г. · If x + 1 is a factor of the polynomial 2x2 + kx, then the value of k is 2. Explanation: Let p(x) = 2x2 + kx. Since, (x + 1) is a factor of ...
