minus-squareLostXOR@fedia.iolinkfedilinkarrow-up47·28 天前Fun fact, omitting the (x-x) zero term and expanding the entire polynomial, you’d get something with 2^25 = 33,554,432 terms. May be slightly excessive!
minus-squarethreelonmusketeers@sh.itjust.workslinkfedilinkEnglisharrow-up8·28 天前Couldn’t you combine a lot of like terms as you went along, though? A polynomial of the order x26 would only have 27 terms.
minus-squareLostXOR@fedia.iolinkfedilinkarrow-up2·28 天前No, because each coefficient is its own variable; they’re not constants.
