You are looking for a number that, when multiplied by the same number, equals 30. This is can be written as x times x, or x 2 = 30. To find the answer, all you have to do is take the square root of 30.
30 ​ is approximately 5.477

The two possible numbers are -6 and 5.
Let's represent the two numbers as x and y
According to the given condition, we have:
x 2 + x = 30
This equation can be rearranged into a quadratic equation:
x 2 + x − 30 = 0
Now, we can factor this quadratic equation:
(x + 6)(x - 5) = 0
This equation has two solutions:
x + 6 = 0
= -6
x - 5 = 0
= 5
So the two possible numbers are -6 and 5.
Complete question:
A number multiplied by itself added to itself equals 30. What are the two possible numbers?
