Answer (3)
5 divided by x squared is a fraction. written mathematically would look like this 5/x^2 In order for this fraction to be true, x CANNOT equal zero. If it does, the fraction is then simply equal to 0. In any other case, x can be both negative and positive because a negative value squared will always be positive. For example if x=1 5/(1)^2=5/1=5 simple. If x=2 though, then the result is much different 5/(2)^2=5/4
what is x ;
The expression x 2 5 represents 5 divided by the square of x . It is valid for all real values of x except zero, as division by zero is undefined. The value of this fraction decreases as x increases, becoming larger for smaller values of x (in absolute terms).
