Another method to solve quadratics

Why isn’t the last picture a square? Is this a square? What about this one?This one?

 What would we need to do to make this a square?  Right, we would need to fill in the missing bottom section.

 We can model a quadratic expression like this  with tiles like this... This is the Split the x piece in 2 and put 1/2  here rest here  The constant (4) goes here

 Each group has some squares and rectangles. Practice showing completing the square for the following problems:  Write the problems on a piece of paper and fill in the blanks when you find the number of small squares needed to complete the square.
