Finding the Numbers

To find the two numbers whose sum is 22 and product is 105, we can use a simple algebraic approach.

Let's denote the two numbers as x and y. We know that: 1. x + y = 22 2. x * y = 105

Solving for the Numbers

We can solve this system of equations to find the values of x and y.

First, let's express one variable in terms of the other using the first equation: x = 22 - y

Now, substitute this expression for x into the second equation: (22 - y) * y = 105

Expanding and rearranging the equation gives us a quadratic equation: y^2 - 22y + 105 = 0

We can solve this quadratic equation to find the values of y.
