for what value of x is the rational expression below equal to zero? x-8/x+8
To find the value of x for which the rational expression is equal to zero, we need to set the numerator equal to zero and solve for x.
In this case, we need to set x - 8 equal to zero:
x - 8 = 0
Now, we can add 8 to both sides of the equation to isolate x:
x = 8
Therefore, the value of x for which the rational expression (x - 8) / (x + 8) is equal to zero is x = 8.
When the numerator of a fraction equals 0, the fraction equals 0.
So what value of X makes the numerator 0?
x-8 = 0. X = ?.
