Question

1. (y+2) x (3y+5)
2. (m-3) x (m+7)
3. (3x+2) x (x-1)
4. ( 2p-3q) x (5p+2q)
5. (3p+7) x (5-2p)
6. (2y+5) x (y-3)
7. (8-y) x (y+3)
8. (3a^2+b^2) x (a^2-b^2)
9. (x^2-x-2) x (x+3)

Answer 1

1. (y+2)(3y+5) = 3y² + 5y + 6y + 10 = 3y² + 11y +10
2. (m-3)(m+7) = m²+7m-3m-21 = m² + 4m - 21
3. (3x+2)(x-1) = 3x² - 3x + 2x - 2 = 3x² - x - 2
4. (2p-3q)(5p+2q) = 10p² + 4pq -15pq -6q² = 10p² - 11pq - 6q²
5. (3p+7)(5-2p) = 15p - 6p² + 35 -14p = - 6p² + p + 35
6. (2y+5)(y-3) = 2y² - 6y + 5y -15 = 2y² - y -15
7. (8-y)(y+3) = 8y + 24 - y² -3y = -y² + 5y + 24
8. (3a² + b²)(a² - b²) = 3a^4 -3a²b² +a²b² - b^4 = 3a^4 - 2a²b² - b^4
9. (x²-x-2)(x+3) = x³+3x²-x²-3x-2x-6 = x³ + 2x² - 5x - 6

Answer 2

1. 3y² + 11 y + 10
2. m² + 4m - 21
3. 3x² + x - 2
4. 10p² - 11pq - 6q²
5. - 6p + p + 35
6.  2y² - y - 15
7. 5y - y² - 3y
8. 3a(pangkat4) - 2a(pangkat2)b(pangkat2) - b(pangkat4)
9. x³ + 2x² + x - 6

semoga benar... maaf ya kalau salah
