Question

factor 625x^4-256

Answer 1

complex

Answer 2

what do you mean "complex"? you can factor as
\[(5 x-4) (5 x+4) (25 x^2+16)\]

Answer 3

can you think of a number that can be taken out of 625 and 256 to reduce those terms? Like the GCM between those two?

Answer 4

if you want to factor further over complex numbers you can also write
\[(5 x-4) (5 x+4) (5x+4i)(5x-4i)\]

Answer 5

find all the zeros, state the multiplicity of each zero
oh and for the problem i asked and i dont think it applies to this question, where we have imaginary numbers..

Answer 6

oh okay
