Question

Find the polynomial function with roots 1, 7, and –3 of multiplicity 2

Answer 1

pretty much the same as the last one, but multiplicity two means it is
\[(x-1)(x-7)(x+3)^2\]

Answer 2

gotcha! thanks!

Answer 3

so the final answer would be x^4+2x+16?

Answer 4

i don't know i didn't multiply
seems unlikely though. hold on

Answer 5

the constant term has to be \(-7\times 9=-63\) so that cannot be right

Answer 6

expanded form is here

Answer 7

are all three of them being squared, or is it just x-3?

Answer 8

i took it to mean that only the zero of 3 had multiplicity two

Answer 9

o.k. then. Thanks for that link!
