Question

The volume of a cube is x³ + 3x² + 3x + k
If its length is x + 1, find k.​

Answer 1

Answer:

GIVEN , X + 1 = 0

==> X= -1

GIVEN ==> X³+3X²+3X+K

PUUTING VALUE OF X IN EQ(1)

==> (-1)³ + 3(-1)² +  3(-1)  + K

==> -1 + 3 -3 +K

==> -1+K =0

==> K = 1

Answer 2

Step-by-step explanation:

ANSWER

If g(x) is a factor of f(x), then f(3)=0 ....(By remainder Theorem)

Thus, f(3)=0
