bantu jawab plisssssssssssssdssssssss, jangan ambil poin doang
Jawaban:
a. 6m²-3m-2-2m²+m+3
6m²-2m²-3m+m-2+3
4m²-2m+1
b.4p²-pq+2q²-7p²-3pq-q²
-3p²+q²-4pq
[tex]a. \\ ( {6m}^{2} - 3m - 2) - (2 {m}^{2} - m - 3) \\ = {6m}^{2} - 3m - 2 - 2m {}^{2} + m + 3 \\ = (6 - 2) {m}^{2} - (3 - 1)m + (3 - 2) \\ = 4 {m}^{2} - 2m + 1[/tex]
[tex]b. \\ (4 {p}^{2} - pq + {2q}^{2} ) - ( {7p}^{2} + 3pq + {q}^{2} ) \\ = {4p}^{2} - pq + 2 {q}^{2} - 7p {}^{2} - 3pq - {q}^{2} \\ = (4 - 7) {p}^{2} - (1 + 3)pq + (2 - 1) {q}^{2} \\ = {q}^{2} - 3pq - 3 {p}^{2} [/tex]
