You can put this solution on YOUR website! You must begin by performing the operations within the parentheses, doing the exponents first.
-(6-2^3-3)^2 + 2 x (-4)
Next, subtract within the parentheses, from left to right:
-(6-8-3)^2 + 2 x (-4)
-(-2-3)^2 + 2 x (-4)
-(-5)^2 + 2 x (-4)
Next, square the (-5), which gives you +25, and multiply 2*(-4)=-8:
-(25) + 2 x (-4)
-25-8
-33
