This means that

Since they both have the same denominator, you can easily subtract the fractions: 
That would equal 1/4:)
hope i helped chu out
What you would do is you would substitute each ordered pair into their respective variables. (ie. for (0,1) you would put 0 where the x is and 1 where the y is) You would then solve the equation. If the equation is not even (ie. 2=5 would not be even but 4=4 would be), you move on to the next ordered pair.
If you follow the process right and you get the equations correct, the answer should be B. (7,-2)
Answer:

Step-by-step explanation:
The given function is

Observe that, the first two factors are from difference of two squares.


We expand the brackets using the distributive property to obtain;


The above function is now in standard form, since the terms are arranged in descending powers of
