Step-by-step explanation:

If x+6 is a factor

x+6=0

then x= -6.

Now placing it in place of x

(-6)³+3(-6)³+4(-6)+a = 0

-216-648-24+a =0

-888+a =0

a= 888 is the answer.

Remember

  • Use BODMAS
  • Brackets of Division Multiplication Addition Subtraction
  • Convert the value of x
  • In odd powers result will be negative
  • In even it will change
  • Remember to change signs if required.
