Pliss jawab make cara ye! 1. Jumlah dari 6x - 3y + 2z dan -9x + 6y + 2z adalah... 2. Jika 5x - 4y + 8 dikurangkan pada 4y - 2x - 4, hasilnya adalah... 3. Hasil

[tex]1.6x - 3y + 2z + ( - 9x) + 6y + 2z \\ = - 3x + 3y + 4z \\ \\ 2.4y - 2x - 4 - (5x - 4y + 8) \\ = 4y - 2x - 4 - 5x + 4y - 8 \\ = - 7x + 8y - 12 \\ \\ 3.(3x + 4y)(4x - 6y) \\ = 12 {x}^{2} - 18xy + 16xy - 24 {y}^{2} \\ = 12 {x}^{2} - 2xy - 24 {y}^{2} \\ \\ 4. \frac{6 {a}^{2}b \times 8a {b}^{3} }{6 {b}^{2} } \\ = \frac{48 {a}^{3} {b}^{4} }{6 {b}^{2} } \\ = 8 {a}^{3} {b}^{ 2} \\ \\ 5. \frac{ 4{x}^{2} + 24x + 35 }{2x + 5} \\ = \frac{(4x + 14)(4x + 10)}{2x + 5} \\ = \frac{(2x + 7)(2x + 5)}{2x + 5} \\ = (2x +7)[/tex]
