(b^2 - 8ab) \ (b^2 - 64a^2)((√8)^2 - 8 * √8 * √2) \ ((√8)^2 - 64 * (√2)^2)(8 - 32) \ (8 - 256) = (-24) \ (-248) = 3\31

      I Think I'm Your Mother
   Joyce is 24 years old. She has a baby daughter, but she can't take care of her baby. The government takes Joyce's baby and gives her to another family. Joyce never forgets her daughter. For 20 years Joyce looks for her. She can't find her. She doesn't know her daughter's new name. She doesn't know her daughter's address.
   When Joyce is 44 years old, she gets a job at a small store. A young woman works with Joyce at the store. The young woman's name is Tammy. Tammy and Joyce are friends. One day at work Tammy begins to cry. "What's the matter?" Joyce asks Tammy. "I feel so sad," Tammy says. "I'm looking for my mother and I can't find her." "I don't understand," Joyce says. "I know your mother. She comes into the store sometimes." "Yes, she's my mother, but she's not my birth mother. I can't find my birth mother because I don't have her name or address. I have only this photo. See? This is me when I was a baby." Tammy shows Joyce the photo. Joyce looks at the photo for a long time. Then she opens her wallet and takes out a photo. It is a photo of a baby girl. Joyce's photo and Tammy's photo are the same. "Tammy," Joyce says. "I think I'm your birth mother." The two women hug for a long time. "This is the best day of my life," Tammy says. Joyce smiles and looks at Tammy. "This is the best day of my life, too," she says.
