3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.

Step-by-step explanation:
 
        
             
        
        
        
What is the modulus of 2 – 3i?
 
        
        
        
You add the numbers of all 4 sides. 
        
             
        
        
        
Take the GCF (-8t) of the given expression.
You'll get -8t(2t-5).
Now, set each equal to zero and solve for x.
-8t = 0 2t-5=0
 t=0 t = 5/2 (Or 2.5 seconds)
