Question

If-1 is the remainder when 3 x cube minus 4mx + 8 is divided by X + 3 find m.

Answer 1

Answer:

Step-by-step explanation:

F(x) =3x³-4mx+8

G(x) =x+3

When F(x) is divided by G(x) remainder is -1

By remainder theory

F(-3) =-1

3((-3)³) -4(-3m) +8=-1

-81+12m+8=-1

12m+8=80

12m=72

m=6
