Algebraic Solution of Equations 1: You can use the sum and product properties to find algebraically the exact solutions of certain equations. For 2124, solve the equation by first transforming it to a product equal to zero and then setting each factor equal to zero. Use the domain [0, 360] or x [0, 2 ]. cos 5 + cos 3 = 0
