Benjamin's response: None of the roots can have multiplicity because the polynomial is cubic and 3 roots are given. Write each root as a linear factor, then multiply the three factors to get the expression for the function.
I cannot see what mc001-1.jpg is, but i assume it is a complex number. so according to the <span>irrational root theorem, if </span>a + √b<span> is a root of a polynomial equation where </span>a<span> and </span>b<span> are rational numbers and √</span>b<span> is an irrational number, then </span>a<span> - √</span>b<span> is also a root
the answer would be the complex number given with the opposite sign before </span>√b.
if this doesn't help and you need more clarification, comment what mc001-1.jpg is and i'll be happy to help.
You'd have 25 6/8 yards of wire left because she took 3 yards from each spool. So that gives us 2 spools of 12 7/8 and when you add them you get 25 6/8.
