Explanation:

(This is a Quadratic equation in the variable x).

Answer 2

One less than the sum of square of a number and twice the number is 0

Explanation:

`x^2+ 2x - 1 = 0`

x represents any number. x^2 represents square of a number

2x represents twice the number

`x^2+2x` can be written as sum of square of a number and twice the number

`x^2+2x-1`

One less than the sum of square of a number and twice the number

`x^2+2x-1=0`

One less than the sum of square of a number and twice the number is 0
