No. Let me try to solve. So x^2+4x-2+x^2-5+x^2+4x-2+x^2-5 must be the equation since we are trying to find the perimeter. Now let's simplify the like terms. Let's add all the x^2. x^2+x^2+x^2+x^2 is 4x^2. Now let's add the variables. 4x+4x=8x. Now let's add the whole numbers. -2+-5+-2+-5 is -14. So our final equation will be 4x^2+8x-14. All you did wrong is that when you add exponents, you only add the bases.
