can u please tell which question are you asking it would better to answer of u specify the question number.ok I will give u the answer via notebook
Answer:
1. 4(3a + 7b) - 6(3a + 7b)
= 12a + 28b - 6(3a + 7b)
= 12a + 28b - 18a - 42b
= -6a + 28b - 42b
= -6a - 14b
2. 8 - 4a - 2a³ + a⁴
= 4(2 - a) - a³(2 - a)
= (2 - a) (4 - a³)
5. 4(2a - 3b)² + 8(2a - 3b)
= 4( 2a² + 3b² - 2.2a.3b) + 16a - 24b
= 4(2a² + 3b² - 12b) + 16a - 24b
= 8a² + 12b² - 48b + 16a - 24b
= 8a² + 12b² + 16a - 72b
= 8a² + 16a + 12b² - 72b
7. 9x(5x - 4y) - 12x²(5x - 4y)
= 9x - 12x²(5x - 4y)
8. 3p(xy + 2) + q(xy + 2)
= 3pxy + 6p + qxy + 2
9. p²(x+y) - q²(x+y) + 2r²(x+y)
= p² + q² + 2r²(x+y)³
10. p³(x - 2y) - p²(x - 2y)
= p³ - p²(x - 2y)²
= p²(p - 1)(x -2y)²
12. 4x² - 3xy - 16x + 12y
= x(4x + 3y) + (-12y - 16x)
= x(4x + 3y) - 4(3y + 4x)
= (4x + 3y)(x - 4)
14. 6ab - b² + 12ac - 2bc
= b(6a - b) + 2c(6a - b)
= (6a - b)(b + 2c)
16. 2ax + bx + 2ay + by
= 2ax + 2ay + bx + by
= 2a(x + y) + b(x + y)
= (x + y)(2a + b)
18. 12x - 8 + 3xy - 2y
= 4(3x - 2) + y(3x - 2)
= (3x - 2)(4 + y)
19. a² + ac + bc + ab
= a² + ab + ac + bc
= a(a + b) + c(a + b)
= (a + b)(a + c)
20. x² + xy + 9x + 9y
= x(x + y) + 9(x + y)
= (x + y)(x + 9)
