okay so the question is as follows!
use X^2+ y^2-6x+8y+ 9= 0
write the equation in standard form!
so here is waht I have done!
X^2+ y^2 -6x +8y+ 9= 0
X^2+ y^2 -6x +8y=-9
now I have to remove the coefiicent from X^2 and y^2
1(X^2-6x) +1( y^2 +8y) =-9
Now I have to complete the squares but I get lost from here I am unsure how to do it! thanks! :)
