• ### Maths Question?

Best answer: 6x - 12 = -3(x - 4)

6x - 12 = - 3x + 12

6x + 3x = 12 + 12

9x = 24

x = 24/9

= 8/3

= 2 2/3

• ### Why does 3(x^2+1)^2 equal 3(x^4+2x^2+1)?

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... show more
