Answer:
Step-by-step explanation:
3+√5 is a root.
so 3-√5 is also a root 
or (x-(3-√5)) is also a factor of f(x)
 
        
             
        
        
        
Answer:
114
Step-by-step explanation:
Since DE and EF are equal, DEF is an isosceles triangles.
In isosceles triangle, two angles are equal.
So,
∠F = ∠D = 33
Sum of interior angles in a triangles is 180,
∠D + ∠F + ∠E = 180
33 + 33 + ∠E = 180
∠E = 180 - 33 - 33
∠E = 114
 
        
                    
             
        
        
        
(5p² - 3) - (2p² - 3p³)
(5p² - 2p²) - 3 + 9p³
3p² - 3 + 9p³
