Question
The difference of two numbers is 1.
The product of the two numbers is 6.
What are the two numbers?
Solution
Let's denote the two numbers as x and y.
From the problem, we have two equations:
-
x - y = 1 (The difference of two numbers is 1)
-
xy = 6 (The product of the two numbers is 6)
We can solve this system of equations step by step:
Step 1: Solve the first equation for x: x = y + 1
Step 2: Substitute x in the second equation: (y + 1)y = 6, which simplifies to y^2 + y - 6 = 0
Step 3: Factor the quadratic equation: (y - 2)(y + 3) = 0
Step 4: Set each factor equal to zero and solve for y: y - 2 = 0 gives y = 2 and y + 3 = 0 gives y = -3
Step 5: Substitute y = 2 and y = -3 into the equation x = y + 1 to find the corresponding x values: x = 2 + 1 = 3 and x = -3 + 1 = -2
So, the two pairs of numbers that satisfy the conditions are (3, 2) and (-2, -3).
