Given expression: 
We need to add the given rational expressions.
First step: Combined like terms in the numerator and kept the common denominator.

Second step they applied : Canceling the like term x^2 and got 
Note: We can't cancel like terms in top and bottom like this.
We can cancel out common factors in top an bottom.

Answer:
2 square root of 2 and -2 square root of 2
Step-by-step explanation:
Write the system of equation based on the problem
"A total of 345 tickets that consists of adult tickets and students ticket were sold" could be written as:
∴ a + s = 345 <em>(first equation)</em>
"<span>the number of student tickets sold was two times the number of adult tickets sold" could be written as:
</span>∴ s = 2a <em>(second equation)</em>
<span>
Solve the system of equation
Substitute 2a as s in the first equation
a + s = 345
a + (2a) = 345
3a = 345
a = 345/3
a = 115
There are 115 adult tickets sold.</span>
