The sum of a number and its square is 182. Find the number.

13 and -14 satisfy this condition

Step-by-step explanation:

Let's represent that number as x

and the square of x is x^2

So,

x + x^2 = 182

Subtract 182 from both sides

x + x^2 - 182 = 182 - 182

x + x^2 - 182 = 0

rearrange the quadratic equation

x^2 + x -182 = 0

let's use the quadratic formula

      or      

a = 1, b = 1, c = -182

      or    

     or        

           or    

    or    

    or    

13 or    - 14

Lets check

13 + 13^2 = 13 + 169

= 182

Also,

-14 + (-14^2) = -14 + 196

= 182

2. never true

3. sometimes

these are pretty self explanatory if you know what supp right and com angles are

actually what is a question i don't understand
