Question

The volume of a cube is x^3 + 3x^2 +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

hi dude



h r u



your answer is here




x+1=0



x^3+3x^2+3x+k



(-1)^3+3(-1)^2+3(-1)+k



-1+3-3+k




-1+k=0




k=1




Thank you
