Solve this equation to obtain their ages. So we want two numbers that multiply together to make 6, and add up to 7. If you rearrange and rewrite this, you'll have x 2 + 2x - 168 = 0. With the quadratic equation in this form: Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b. If the product of both Allan’s and Clara’s ages is 168, how old is Clara? As soon as you read this, this equation will ring a bell: x(x + 2) = 168. Try this simple question: Alan is 2 years older than Clara. Solving quadratics by completing the square.
