Question

What two numbers add up to 4 and multiply to 2

Answer 1

The numbers that add up to 4 and multiply to 2 are 2 and 2.

How did we get the values?

Let's call the two numbers
`\(x\)` and
`\(y\)`. The problem can be expressed as a system of equations:

`\[x + y &= 4 \quad \text{(sum of the two numbers is 4)}`

`x2 &= 4 \quad \text{(product of the two numbers is 4)}\end{align*}`

To find the values of
`\(x\)` and
`\(y\)`, you can solve this system of equations. One possible solution is
`\(x = 2\)` and
`\(y = 2\)`, because
`\(2 + 2 = 4\)` and
`\(2 * 2 = 4\)`. Therefore, the numbers that add up to 4 and multiply to 2 are 2 and 2.
