Construct a proof by contradiction for the statement by selecting sentences from the following scrambled list and putting them in the correct order. Squaring both sides of the equation gives that r + s = r + 2rs + s. But this is a contradiction because r and s are positive. Squaring both sides of the equation gives that r + s = r + 2 r s + s. By the zero product property, at least one of r or s equals 0, which implies that r or s equals 0.By the zero product property, at least one of r or s equals 0.Simplifying the equation gives that 0 = 2 r s . Simplifying the equation gives that 0 = 2rs.
