Question

Help!!!
x+2=2

Answer 1

add -2 on both the sides of the equation
x+2-2=2-2
+2 and -2 get cancelled out and 2-2=0
therefore
x=0

Answer 2

Now a real question, if you can help me
How do I know whether the equation is parabola, ellipse, or a circle?

Answer 3

Can you help me?

Answer 4

If x² and y² both have the same coefficients like x² + y² or 3x² + 3y², then it is a circle.

If x² and y² both have different coefficients that have the same sign, like 4x² + 9y², or x² + 16y², then it is an ellipse.

If x² and y² have different signs, like 25x² - 9y², or 16y² - x², then it is a hyperbola.

If the equation has either x² and y², but not both, then it is a parabola.
