Do you mean multiplying polynomials? If so here's a way (FOIL but more visual) that I remember from Algebra 1:

Good Luck!

@PatrickOritzJauregui  I don't really get it. could you explain?

@DaraUdobong Sure!

The image I put up is a way that I always multiplied out polynomials, and it serves me best in the shortest amount of time.

Here, let me add the image again to explain it.

The problem is: Evaluate/Expand (2x + 3)(x - 7):

• Make a 2x2 square, like the one below (or a 3x3 with the given statement)

                     2x     +   3
                  ________ _______
           x     |        |       | 
                 |        |       |
                 |-----------------
          -7     |        |       |
                 |        |       |
                 ------------------

• Multiply it out! In the top left of the 2v2 (middle for 3v3), it's the first term that should always be first and at the highest order!

                    2x     +   3
                  ________ _______
           x     |        |       | 
                 |  2x^2  |       |
          -7     |-----------------
                 |        |       |
                 |        |       |
                 ------------------

• Multiply out the rest, and what's cool about this square method is that the square sections diagonally adjacent are to the same order, and must be combined/crossed out (blue in pic far below)

                    2x     +   3
                  ________ _______
           x     |        |       | 
                 |  2x^2  |   3x  |
          -7     |-----------------
                 |        |       |
                 |  -14x  |  -21  |
                 ------------------


              Then:   (2x^2) + 3x -14x -21
Combine Like Terms:   (2x^2) -11x -21

Here's the image again, final except not written out

Hope that cleared it up, and this works really well for me (better than normal FOIL and just as fast in my opinion).

Good Luck!
