What are the three question?
        
             
        
        
        
 Exponent is the expression in where you convert product factor expression into a shorter expression. So really you use  it to make the question simpler and shorter(easier to understand).

Find the Greatest Common Factor (GCF)
GCF = 2xy
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)
Simplify each term in parenthesis 
2xy(4x^2 - 4x - 15)
Split the second term in 4x^2 - 4x - 15 into two terms
2xy(4x^2 + 6x - 10x - 15)
Factor out common terms in the first two terms, then in the last two terms;
2xy(2x(2x + 3) -5(2x + 3))
Factor out the common term 2x + 3
<u>= 2xy(2x + 3)(2x - 5)</u>
 
        
             
        
        
        
Answer:
x = 88 degrees
Step-by-step explanation:
Its really easy. All you have to do is subtract all the known angles from 360 since a quadrilateral has 360 degrees
360 - 106 - 114 - 52 = 88
Hope this helped!
