Question

If the double of a natural number is equal to the square of the number, find the number.​

Answer 1

2

Explanation:

Assume, that the number is x

Let's write an equation according to the given information:

`2x = {x}^(2)`

`{x}^(2) - 2x = 0`

Let's solve this incomplete quadratic equation:

`x(x - 2) = 0`

x = 0 or x - 2 = 0

x = 2

Since O isn't a natural number, the answer is 2
