Philip and Barbara are 8 meters apart because 5+3=8 so it will make 8 meters
        
             
        
        
        
This does not look easy to factor, so I'd suggest using the quadratic formula:
        -1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
                               2*3
         -1 plus or minus sqrt(61)
    = ------------------------------------
                             6
Thus, there are 2 real, unequal, irrational roots / solutions.
