# How do you simplify #(6x^2)/(4x^2) - 54/36#?

##### 1 Answer

Just in case simplification gives you a problem I have shown every step. Also a trick to test for divisibility by 3

Answer is 0. Becomes undefined at

#### Explanation:

Write as:

But

1 times anything does not change the value. So we can disregard the

Now we have:

Notice that all the numbers are even. If simplifying gives you a problem you can use this type of approach:

Notice that for 27 we have

Notice that for 18 we have the same thing:

So we can divide both top and bottom by 3
