Question

find the value of m for which (x+2) is a factor of -x^3+2x+3m​

Answer 1

Answer:

m=   - 4/3

Step-by-step explanation:

Answer 2

ok,

Sol: x+2 = 0 , x =-2

-x³ + 2x + 3m = 0

(-2)³ + 2 (-2) + 3m =0

-8 + (-4) + 3m =0

-8 -4 + 3m = 0

-12 + 3m = 0

3m = 12 / 3

m = 4

Ans. The value of m is 4
