I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
        
             
        
        
        
Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them: 
   ✧ 4 - 16 = -12
   ✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them: 
   ✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

44.120,44.102,44.012 because they are all 44 and look at the number next to 44 it's 0 1 1 and the ones are bigger and the first Bremer the the least move to the second number 0 2, 2 is bigger than 0 so, 44.120 is the biggest
