6 is added to the square of a number, the result is 55.
To find :-
Find the number ?
Solution:-
Let the number be X
The square of the number = X^2
On 6 is adding to the square of the number =
X^2 + 6
The result = 55
=> X^2 + 6 = 55
=> X^2 = 55 - 6
=> X^2 = 49
=> X =±√49
=> X = ±7
=> X = 7 or -7
Answer:-
The required number for the given problem is 7 or -7
Check :-
If the number is 7 then
Square of 7 = 7^2 = 49
On adding 6 to it = 49+6 = 55
If the number is -7 then
Square of -7 = (-7)^2 = 49
On adding 6 to it = 49+6 = 55
