Matematika Suku suku yang sejenis dari: 1.9a²-3ab+4a+6ab-18a 2.5x²+6xy-8y²-2xy+9y² 3.8p²q²-p²q + 12pq+5pq+3p²q

Suku suku yang sejenis dari:
1.9a²-3ab+4a+6ab-18a
2.5x²+6xy-8y²-2xy+9y²
3.8p²q²-p²q + 12pq+5pq+3p²q

[tex]1. \: \: 9 {a}^{2} - 3ab + 4a + 6ab - 18a \\ = 9 {a}^{2} - (3ab + 6ab) + (4a - 18a) \\ = 9 {a}^{2} - 9ab + ( - 14a) \\ = 9 {a}^{2} - 9ab - 14a[/tex]

[tex]2. \: \: 5 {x}^{2} + 6xy - 8 {y}^{2} - 2xy + 9 {y}^{2} \\ = 5 {x}^{2} + (6xy - 2xy) - (8 {y}^{2} + 9 {y}^{2} ) \\ = 5 {x}^{2} + 4xy - 17y ^{2} [/tex]

Semoga membantu
