Write a polynomial that describes the area of the shaded region.

The area of the shaded region is ========================================================

Explanation:

For now, let's ignore the 4 by 4 smaller square.

The orange larger square has area of...

You can use the FOIL rule to get the same result. The box method is also a visual handy tool.

No matter which method you use, the area of the orange square is if we ignore the 4 by 4 portion.

However, we do have that white portion to take away from the orange square. So we'll subtract off 4*4 = 16 square units to end up with

The orange shaded region has area of

If we knew what the value of x was, then we could find an actual numeric result rather than a polynomial like this.

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

lol.

it's ok we all do this sometimes.
