Use the zero product property to find the solutions to the equation x2 – 13x + 30 = 0.

Factor the quadratic by finding two numbers that multiply to 30 and add to −13: −10 and −3. Thus, x² − 13x + 30 = (x − 10)(x − 3) = 0. By the zero product property, x − 10 = 0 or x − 3 = 0, so x = 10 or x = 3. Choice D gives these solutions.
