Best ResponseYou've already chosen the best response.1\[x^22x+8y + 25=0 \]\[\implies x^22x=8y  25\]\[\implies x^22x+1=8y  25+1\]\[\implies \left( x1 \right)^2=8y  24\]\[\implies \left( x1 \right)^2=8(y +3)\]

Best ResponseYou've already chosen the best response.0Okay thank you. How can I decide what to do? I mean I never know what steps to take?

Best ResponseYou've already chosen the best response.1First move all the x terms on one side & all the nonx terms on the other... Then you need to add to both sides a number that would make the x side a perfect square. Generally if you have x^2+ bx you would add: \[\left( \frac b2 \right)^2 or\ {b^2 \over 4}\]
