-x^ two *(two *x + eight) - two *x*(x + four)^ two = zero
minus x squared multiply by (2 multiply by x plus 8) minus 2 multiply by x multiply by (x plus 4) squared equally 0
minus x to the power of two multiply by (two multiply by x plus eight) minus two multiply by x multiply by (x plus four) to the power of two equally zero
-x2*(2*x + 8) - 2*x*(x + 4)2 = 0
-x2*2*x + 8 - 2*x*x + 42 = 0
-x²*(2*x + 8) - 2*x*(x + 4)² = 0
-x to the power of 2*(2*x + 8) - 2*x*(x + 4) to the power of 2 = 0
