Question

if x+2 is a factor of x³+2ax²-16 then value of a is​

Answer 1

Answer:

if x+2 is a factor of x³+2ax²-16 then value of a is

Step-by-step explanation:

If x + 2 is a factor of x3 – 2ax2 + 16, then value of a is. 3. 1.If x + 2 is a factor of x3 – 2ax2 + 16, then value of a is. 3. 1.

Answer 2

Step-by-step explanation:

let x+2=0

x=-2

so,

(-2)³+2a(-2)²-16=0

-8+4a-16=0

-24+4a=0

4a=24

a=24/4

a=6
