k such that 3 is the remainder when f(x)=x to the 4 power minus 4xcube minus 8xsquare minus 7x plus 1. Tapos which of the following binomial factor of 2xcube plus 5xsquared minus 10x plus 16.

Answer 1

Try using math symbols. I believe you meant

f(x) = x^4-4x^3-8x^2-7x+1

No idea what "Tapos" means, but
2x^3+5x^2-10x+16 used as a divisor does not leave a remainder of 3.

Also, what does "k" have to do with any of the other stuff?

Maybe you can fill in the missing information and say just what it is you want to know ...
