Explanation:

The (x-a) in the denominator causes a problem if we tried to simply directly substitute in x = a. This is because we get a division by zero error.

The trick often used for problems like this is to rationalize the numerator as shown in the steps below.

At this point, the (x-a) in the denominator has been canceled out. We can now plug in x = a to see what happens

There's not much else to say from here since we don't know the value of 'a'. So we can stop here.

Therefore,

no, because the sides are not congruent
