Jill is designing a picture frame for an art project. she plans to have a square piece of glass (x inches by x inches) in the center and surround it with a decorated ceramic frame (648-07-02-00-00_files/i016.jpg inches by 648-07-02-00-00_files/i0160001.jpg inches), which will also be a square. jill determines that she needs 27 square inches of material for the frame.
write a polynomial equation that models the area of the frame.

a. x 4 −7x2 + 9 = 27
c. x 4− 7x2 + 9 = 0
b. x3 −3x2 + 3 = 27
d.3x3− x2− 9 = 27
