F(x)=x^(3)-19x-30
Show that (x-2) is a factor of f(x)

What would the rule be for the reflection of y=-3

Fast! find the length of cu. the triangles are similar. show your work.

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
