<u>Concept:</u>
When we encounter questions that ask us to simplify expressions that consist of multiple parentheses, it is suggested to use the FOIL method to ease the process.
<u>Solve:</u>
Given
(x - 3) (x + 5)
Expand parentheses
x² + 5x - 3x - 15
Combine like terms
x² + (5x - 3x) - 15
x² + 2x - 15
Hope this helps!! :)

Answer: <em>x</em>=12
Explanation:
In a parallelogram, adjacent angles equals 180 (consecutive angles). Therefore, (132-x)+(6x-12)=180
Simplify:
-x+6x+132-12=180
5x+120=180
5x=60
x=12
