Best ResponseYou've already chosen the best response.0ok srry im just learning this ok and then gives u this [−3x−2]^2=2^2

electrokid

Best ResponseYou've already chosen the best response.1that is ok. well, this first gives \[3x2=2\] so, we the square it like you just wrote above

Best ResponseYou've already chosen the best response.1\[(3)^2(x2)^2=(2^2)\] notice that the absolute sign has disappeared

Best ResponseYou've already chosen the best response.1or to avoid squaring, you can remove the abolute sign in two ways...... \[3x2=2\impliesx2={3\over2}\]

Best ResponseYou've already chosen the best response.1this gives the above form.. now, by definition of ABSOLUTE value, can it ever become negative?
