Q. What is the center of the hyperbola x2−y2−9=0?(_,_)
Rewrite Equation: Rewrite the equation to isolate the constant term on one side.Move the constant term to the right side of the equation.x2−y2−9+9=9x2−y2=9
Standard Form Conversion: Convert the equation into the standard form of a hyperbola.Divide both sides of the equation by 9 to get the standard form.9x2−9y2=999x2−9y2=1
Identify Center: Identify the center of the hyperbola.The standard form of a hyperbola is (x−h)2/a2−(y−k)2/b2=1, where (h,k) is the center.In our equation, x2/9−y2/9=1, we can see that h=0 and k=0.Center of the hyperbola: (0,0)
