Factor bingo The students in Ms. Nomial’s Algebra class like to play Factor bingo. Every student gets a bingo card to play. The way Ms. Nomial plays it is that she writes polynomials on the board, the students have to fully factor each polynomial. After they have factored the polynomial they cover any of those factored that they have on their card. To win the games the first student must cover five in a row, column, or diagonal wins factor bingo. Ms. Nomial wrote $ polynomials on the board which are 20x^2-13x +2, 12x^3y-75xy^3, 6x^2+3y^2-8x-4y, and 2x^2+23x-24. In order to solve 20x^2-13x+2, I looked for the multiples of 20 and 2. Then I made sure they added up to 13. To do so I multiplied 5 x 4=20 and 2 x 1= 2. This makes the solution (5x-2) (4x-1). Now I solved 12x^2=23x-24. I did the same process and found the multiples of 12, 24, next I multiplied 3 and 4 and 6 and 2 to make 12, as for multiplies of 24 I remembered 8X3 and 6x4. I later used the guess and check method. I first tried 3 X 4 and 8 x 3. I checked my work by used foil (first, outside, inside, last), I succeeded in my first try. Next I solved 6x^2+3y^2-8x-4y. once again I used the same process I discovered the multiplies of 6x^2 and 4y which answer is( 3^2-4) (2x+4. So I double checked using foil. So now I have solved 6 squares which are C,H,I,X,O,V and w. The only polynomial that can possible give me a winning card is 2x (3x+11). The only square that isn’t filled is 2x and 2x and 3x+11 in the row were I have placed 3 squares covered. Making it the answer to win factor bingo. This would be something I would like to play in class. This would be fun yet educational and a nice reminder for factoring.
