Textbook Problem

Identify the type of conic section whose equation is given and find the vertices and foci.

28. y2 − 2 = x2 − 2x

To determine

To Find: The type of conic section, vertices, and foci for the equation y2−2=x2−2x .

Explanation

Given:

The equation is as follows.

y2−2=x2−2x (1)

Rewrite the equation.

y2−x2+2x+1=2−1

Factorize the above equation as below.

y2−(x−1)2=1

Divide the above equation by (1).

y21−(x−1)21=11

y21−(x−1)21=1 (2)

Then, compare the equation (2) with the standard equation of hyperbola.

y2a2−x2b2=1 (3)

Therefore, the type of conic section is hyperbola_ .

Calculation:

Compute the center of the hyperbola using the equation.

(y−k)2a2+(x−h)2b2=1(y−0)21+(x−(−1))21=1

Therefore, the center of the hyperbola (h,k) is (0,1) .

Substitute the value 1 for a2 and 1 for b2 in equation (3).

a2=1a=1

b2=1b=1

Compute the vertices
