Question

Oblicz i rozpisywać. wzór skróconego mnozenia.

Answer 1

Nie wiem czy dobrze widze :)
1. [-2(3-2m)]^2
[-6+4m]^2=16m^2-48m+36
2. [2(4m-1)]^2
[8m-2]^2=64m^2-32m+4
3. [-3(4-3m)]^2
[-12+9m]^2= 81m^2-216m+144
4. (m-2)^2 -4(m-2)(m+2)
m^2-4m+4-4(m^2-4)= m^2-4m+4-4m^2+16=-3m^2-4m+20
5. (2m-3)^2-3(2m+3)^2
4m^2-12m+9-3(4m^2+12m+9)=4m^2-12m+9-12m^2-24m-27=-9m^2-36m-18
6. (3m+1)^2+2(2m-3)^2
9m^2+6m+1+2(4m^2-12m+9)= 9m^2+6m+1+8m^2-24m+18=17m^2-18m+19
