In summary, the conversation is about finding the x-intercept in an equation and the use of the term "x-int". The term may have different meanings in mathematics and it is important to be clear when asking for help. The conversation also touches on the importance of having a good attitude when seeking assistance.

The what? Why do some people think everybody understand their short writings?

x-intercept. And how don't you know what x-int mean? In calculus, int stands for intercept. And maybe if u took your time and saw the tag, you'd know what it means.

You can't always assume this: even in an area of mathematics where everything is defined rather clearly, sometimes people have different terms for the same thing and if you come across this situation, don't be too surprised.

First: that is false: int may mean "integral", "integer", "intercept", etc., second: yes, I was almost sure what you meant, but this is

mathematics and you're supposed to be crystal clear, third: it is, imo, a very bad idea to ask for help with such a nasty attitude.

jasn4real, why don't you start with the fact that if a/b=0, then a=0?
 

FAQ: Finding the X-Intercept in a Rational Function: (x^2 +1)/ (x^2 -4)

How do I find the x-intercept of an equation?

To find the x-intercept of an equation, set y equal to zero and solve for x. The resulting value of x will be the x-intercept.

What is the purpose of finding the x-intercept of an equation?

The x-intercept of an equation represents the point where the graph of the equation crosses the x-axis. It is useful in determining the roots or solutions of the equation and in graphing the equation.

Can I use any method to find the x-intercept of an equation?

Yes, there are several methods that can be used to find the x-intercept of an equation, such as substitution, elimination, or graphing. The most appropriate method will depend on the complexity of the equation.

What if the equation has multiple x-intercepts?

If the equation has multiple x-intercepts, you can find each intercept by setting y equal to zero and solving for x. In some cases, it may be helpful to graph the equation to visually determine the number and location of the intercepts.

Can I use the x-intercept to find the y-intercept of an equation?

No, the x-intercept and y-intercept are two different points on the graph of an equation. To find the y-intercept, set x equal to zero and solve for y. The resulting value of y will be the y-intercept.
