You can learn them in a song like type or you should learn and write them and paste in your bedroom so that you can see it before you go to bed and after you
2. ( a - b)2 = a2 - 2ab + b2
3. (a + b ) ( a - b ) = a2 - b2
4. ( x + a ) ( x + b ) = x2 + ( a + b) x + ab
5. (x + a ) ( x - b) = x2 + ( a -b ) x - ab
6. ( x -a ) ( x + b ) = x2 + ( b - a ) x - ab
7. ( x - a ) ( x - b ) = x2 - ( a + b ) x + ab
8. ( a + b )3 = a3 + b3 + 3ab ( a + b )
9. ( a - b )3 = a3 - b3 - 3ab (a - b )
10. (x + y + z)2 = x2 + y2 + z2 + 2xy +2yz + 2xz
11. (x + y - z)2 = x2 + y2 + z2 + 2xy - 2yz - 2xz
