Answer 2

Step-by-step explanation:

=>√6 -4x -x² = x + 4​

=>√6-4x-x²-x-4=0

=>-x²-4x-x-4+√6=0

=>-x²-5x-4+2.4=0

=>-x²-5x-1.6=0

=>-x²-5x=1.6

=>-x²-5x+(5/2)²=1.6+(5/2)²

=>(-x+5/2)²=1.6+25/4

=>(-x+5/2)²=31.4/4

=>-x+5/2=±√31.4/4

=>-x+5/2= -√31.4/4        or     =>-x+5/2= +√31.4/4

=>-x= -√31.4/4-5/2                  =>-x=√31.4/4-5/2

=>-x= -√31.4 - 5 ÷2                 =>-x=√31.4 - 5 ÷ 2

=>x=√31.4 - 5 / 2                    =>x= -√31.4+5 / 2

      hope it helps mark s brilliant.
