3m(m-4)(5m+2)-m(2m+3)(4-3m)= Zapisz w jak najprostszej postaci. Mnożenie sum algebraicznych.

3m(m-4)(5m+2)-m(2m+3)(4-3m)= 3m(5m²+2m-20m-8)-m(8m-6m+12-9m)= 15m³+6m²-60m²-24m-8m²+6m²-12m+9m²= 15m³-47m²-36m

3m(m-4)(5m+2)-m(2m+3)(4-3m)= = (3m²-12m)(5m+2)-(2m²+3m)(4-3m)= =15m³+6m²-60m²-24m-(8m²-6m³+12m-9m²)= =15m³-54m²-24m+m²-6m³+12m= =9m³-53m²-12m

3m(m-4)(5m+2) -m(2m+3)(4-3m)= 3m*5m+2m-20m-8-m*8m-6m+12-9m=15m+2m-20m-8-8m2(kwadrat)-6m+12-9m=4-8m2
