then k=?
​

Answer 1

$\huge\boxed{\dag\sf\blue{Given}\dag}$

• (x+1) is a factor of (2x²+kx)

$\huge\boxed{\dag\sf\blue{To Find}\dag}$

• Value of k=?

$\huge\boxed{\dag\sf\blue{Solution}\dag}$

It is given that,

(x+1) is a factor .

: . x= -1

: . 2x²+kx=0

: . 2(-1)²k(-1)=0

: . 2-k=0

: .k=2

Therefore the value of k is 2.

Answer 2

Answer:

X + 1 = 0

X = -1

2 × (-1) ^2 + k ×-1

2 - K = 0

K = 2
