When I solved for this, I got 3(x^2+1)^2 equals 3(x^4+1), and then 3x^4+3, but the correct answer is 3(x^2+1)^2 equals 3(x^4+2x^2+1), and then 3x^4+6x^2+3.
Where does 2x^2 come from? I multiplied the exponent by the exponents in the parenthesis and got x^4 and 1^2. This really puzzles me, and this has resulted in...
