1. ## Algebra blocks

What algebra blocks would you need to order from the Math Warehouse
so that you can build a square whose edges are all X + 4 units long?

$(x+4)^2 = x^2 + 8x + 16$

one $x^2$ block

eight $x$ blocks

16 unit blocks

3. How do you solve it so easily?
I was trying to draw the blocks.

Thank you!!!!!
