What is the radius of a circle with the equation x2 + y2 – 14x + 10y = 250?

The equation of circle is $\"\"$ .

$\"\"$

$\"\"$ $\"\"$ $\"\"$

$\"\"$

$\"\"$ .

The standard form of circle equation is $\"\"$ . $\"\"$

Compare the $\"\"$ with standard form of circle equation.

Here $\"\"$ and $\"\"$ .

Therefore, the radius of the circle equation is $\"\"$ . $\"\"$ $\"\"$

To change the expression into a perfect square trinomial $\"\"$ add (half the x coefficient)² and add (half the y coefficient)² to each side of the expression.
