Answer:
The second choice is the correct one.
Step-by-step explanation:
20x^4 - 45x^2
GCF is 5x^2, so the factors are:
5x^2( 4x^2 - 9)
Now 4x^2 - 9 is the differencr of 2 squares:
 4x^2 - 9 = (2x + 3)(2x - 3)>
 
        
             
        
        
        
Answer:
x= 3 + , 3 -
, 3 -
Step-by-step explanation:
You use the quadratic formula to get x= 
Then you simplify and get the answers x= 3 + , 3 -
, 3 -
  
  
 
        
                    
             
        
        
        
The two numbers are (5+ √(129))/2 and (5-√(129))/2.
(5+ √(129))/2+ (5-√(129))/2= 5
(5+ √(129))/2* (5-√(129))/2= -26
Hope this helps~
