Please help me!!!!! A number is squared, and then three is added to its square. The result is 228. What is the number?

OpenStudy (herpderp):

Let x = that number. x is squared so, x^2, and three is added so: x^2 + 3 = 228

OpenStudy (herpderp):

can you do the rest?

OpenStudy (sky7133):

15^2 + 3 = 228

OpenStudy (herpderp):

Correct :D

OpenStudy (herpderp):

So the number is 15
