Unformatted text preview: 23 x – 2 x 2 = 60 Rewriting this equation in standard quadratic form gives 2 x 2 – 23 x + 60 = 0 Solving this quadratic equation using factoring gives (2 x – 15)( x – 4) = 0 Setting each factor equal to 0 and solving gives With each x value we can find its corresponding y value. If , then or . If x = 4, then or . Therefore, this problem has two sets of solutions. The number being multiplied by 2 is , and the number being multiplied by 3 is , or the number being multiplied by 2 is 4 and the number being multiplied by 3 is 5....
