  1. Graph the following equations. Some of them will need to be changed into a more useful form. Homework Help ✎

    1. 4(x2 − 10x + 25) + 9(y2 − 8y + 16) = 36

Use the squared binomials to find the center and the denominators to find the edges of the graph.

Complete the squares for the numerators to find the center.

See part (a).

Complete the squares.

4(x − 5)2 + 9(y − 4)2

Divide both sides by 36.

See part (a).
