Circle Ellipse Parabola Hyperbola

STANDARD FORM TO GENERAL FORM OF CIRCLE

Input the value of your equation.

Example: (x-2)² + (y+1)² = 9

Put the center of x(h):
Put the center of y(k):
Enter radius:

Here's the answer:

REMINDER:

Prepare your pen and a piece of paper for writing your answers.

Example: (x-2)²+(y-3)²=4

Step 1: Expand (x-2)²:

✅ square the x = x²

✅ multiply the -2 to x then multiply it to 2 = -4x

✅ square the -2 = 4

✅ = x² - 4x + 4

Step 2: Do the same in y, then put it together

= x² -4x + 4 + y²- 6y + 9 = 0

Given:

(x -)^{2} + (y -)^{2} =

Step 1: Expand the perfect square binomial of the coefficient x and coefficient y.

Step 2: Put the constant in the left side of the equation and change its sign. Combine the like terms and equate to zero the equation.

Step 3: Arrange it to the general equation of circle.
