What is a positive number that equals 30 when added to it squared

5

Step-by-step explanation:

Let x represent the number, then

x² + x = 30

x² + x - 30 = 0      

(x + 6) (x - 5) = 0

x + 6 = 0   x - 5 = 0

 x = -6        x = 5

not valid since the restriction is that x > 0 (a positive number)

So, x = 5
