Answer:
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution

80 + 30
then add
80 + 30=110
then add the numbers you left out
3+ 4 = 7
and you get 117
or you can round up
90 + 40
90 + 40=130
then you subtract the numbers you added on
90 - 83 = 7
40 - 34 = 6
then you add those and subtract from 130 and you get 11Answer here
