Remember what you made y equal to and put it back in: This gives you For number 1 get the same denominator by cross multiplying: = The denominators cancel and the LHS is the difference of two squares:
How does getting this expression prove that = ? Are you not meant to make the first expression look like the second one? Thanks,
Follow the listed steps: Take that second equality, cross-multiply, and simplify using the listed identities. What do you get?
Hello, Tweety! Prove these identities: . . Multiply the left side by The left side is: .
