Learning Targets
I can discuss the algebraic properties of addition and multiplication, which will help identify "legal maneuvers" in solving.
I can use an area model to identify and create equivalent expressions, which will help me in solving.

Use an area model to find an equivalent expression.
Extend: Prove (without graphing) thaty = (x4)(x+6)y = x2 + 2x 24y = (x+1)2 25
all describe the same parabola.
