Find a polynomial function of degree 3 with the given numbers as zeros.
5, sqrt3, sqrt3
Would this work as a function for this problem? Please help. Thanks!
f(x) =(xr1) (xr2) (xr3)
=(x(5)) (xsqrt3) (xsqrt3)
(x+5)) (xsqrt3) (x+sqrt3)

Yes, this works.
You may be expected to expand the terms to the standard polynomial form. Note that the last two factors are of the form (xa)(x+a) which expands conviently to two terms.

Thanks I will keep that in mind.
