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?

Best ResponseYou've already chosen the best response.1\[\Large{32x6=12\\\text{divide both sides by 3}\\ 2x6=4\\\text{to get rid of absolute sign, we get two possible answers}\\\;\\ 2x6=4\qquad{\rm AND}\qquad2x6=4\\ 2x=4+6\qquad\qquad\qquad2x=4+6\\ 2x=10\qquad\qquad\qquad\quad2x=2\\ \boxed{x=5}\qquad\qquad\qquad\quad\boxed{x=1}} \]

Best ResponseYou've already chosen the best response.1check, plug in "x=" those numbers in the given problem on the left side. That should give you the right side.
