If the sum of a number and its square is 182, what is the number ?

- 14 or 13

Step-by-step explanation:

let the number be n then it's square is n² and

n² + n = 182 ( subtract 182 from both sides )

n² + n - 182 = 0 ← in standard form

(n + 14)(n - 13) = 0 ← in factored form

Equate each factor to zero and solve for n

n + 14 = 0 ⇒ n = - 14

n - 13 = 0 ⇒ n = 13

As a check

(-14)² - 14 = 196 - 14 = 182

13² + 13 = 169 + 13 = 182
