Yes there is an error in this statement.
because x^2 = 25
so x = 5...this is one condition
Another condition is x = -5
(-5)^2 = 25 (this is also true)

Another condition is x = -5
(-5)^2 = 25 (this is also true)
You can use the fact that the square of negative number is positive.
There is error in the fact that x = 5 since square of -5 too is 25.
What is the square of a number?
Square of a number is that number multiplied by that number itself.
It is a known property that negative number times a negative number is a positive number.
Thus, if there are two numbers 'a' and '-a', then we have:
[tex]a^2 = (-a)^2 = a^2[/tex]
What is the error in the given statement?
Since x squared is 25, then there are two possibilities. x = 5 and x = -5. Thus, it is wrong to only say that x = 5. We must also specify the other case of x = -5.
