3. Andre and Elena are solving this system of equations:
y = 3x
y=9x – 30
- Andre's first step is to write: 3x = 9x - 30
- Elena's first step is to create a new system:
3y=9x
y = 9x - 30
Do you agree with either first step? Explain your reasoning.

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
