Christina bought a pair of shoes that was on sale for 15% off the original price. If the regular price of the
shoes was $84, which strategy will determine how
much money did Christina paid for the shoes?

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
