Use Pythagorean Theorem of a^2 + b^2 = c^2 where a and b are the legs of the triangle set up by the house height and the ground, and c is the hypotenuse or how long the ladder is. C is going to be our unknown.

Just plugging in you get 25^2 + 35^2 = c^2. Simplify to 625 + 1225 = c^2. Simplify again to 1850 = c^2. The square root both sides to isolate the variable c. C = sqrt(1850) or approximately 43.0116 feet if rounded to 4 decimal places.

The ladder is approximately 43.0116 feet long.

Suppose we have a generic equation of the form:
$ax ^ 2 + by ^ 2 + ax ^ 2 + cx + dy = f
$

1) The first thing you must do to complete squares is to group similar terms of the form:
$ax ^ 2 + cx + by ^ 2 + dy = f
$

2) The second step is to complete the squares.

3) The third step is factor the quadratic equation

4) The fourth step is to identify the center and the radius

Answer:
the first step in finding the center of the circle by completing the square is:
C group like terms
