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) =(x-r1) (x-r2) (x-r3) =(x-(-5)) (x-sqrt3) (x--sqrt3) (x+5)) (x-sqrt3) (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 (x-a)(x+a) which expands conviently to two terms.

Thanks I will keep that in mind.
