Need help with Advance Functions (Pre Calculus)

OpenStudy (anonymous):

When \[x^6+x^4-2x^2+k\] is divided by the remainder is 5. Find the value of k.

OpenStudy (anonymous):

my bad its divided by 1+x^2

OpenStudy (anonymous):

Take long division first ( or synthetic); what do you get?

OpenStudy (anonymous):

x^4-2

OpenStudy (anonymous):

no way!! must have k in . Redo, please

OpenStudy (anonymous):

what do u mean

OpenStudy (anonymous):

the whole result should be \( x^4 -2 +\dfrac{2+k}{x^2+1}\), right?

OpenStudy (anonymous):

the answer is 3

OpenStudy (anonymous):

of course, but you should know that the remainder is the numerator of the last term. so that, by given, that remainder =5 or 2+k =5 to get k =3

OpenStudy (anonymous):

one sec let me try the dividend=divisor x quotient + remainder method.

OpenStudy (anonymous):

yup got it :D
