-2w (w + 8)
 Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
 -2w (w + 8) = 0
 The roots are then:
 w1 = 0
 w2 = -8
 Assuming you only have to rewrite the expression, the answer is:
 -2w ^ 2 -16w
 Answer:
 w1 = 0 
 w2 = -8
 -2w ^ 2 -16w
        
             
        
        
        
The answer is 6.5t2+0.5t−5.5 , it’s simplified
        
                    
             
        
        
        
Sqrt -13  = sqrt13 i
sqrt  -26  =  sqrt2 * sqrt13i 
sqrt-13 * sqrt -26  = sqrt2 * 13*  i^2  = -13 sqrt2 (because i^2 = -1)
answer is -13 sqrt2
