Of two positive numbers, the larger number is 8 more than the smaller number, and their product is 240. What is the smaller number?

Answer and explanation

Correct answer: 12

Let the smaller number be \(x\). Then the larger number is \(x+8\), so \(x(x+8)=240\). This gives \(x^2+8x-240=0\), or \((x-12)(x+20)=0\). Thus, \(x=12\) or \(x=-20\); since the numbers are positive, \(x=12\) is the valid answer. Check: \(12\times20=240\). Remember that 20 is the larger number, not the smaller one.
