Answer 1

$\huge\boxed{Answer}$

(i) 2r(y - x) + s(x - y)

2r(y - x) - s(y - x)

(2r - s) (y - x)

(ii) 16(21 - 3m)² - 12(3m - 21)

16(21 - 3m)² + 12(21 - 3m)

4(21 - 3m) { 4(21 - 3m) + 3 }

4(21 - 3m) (84 - 12m + 3)

4(21 - 3m) (87 - 12m)

12(21 - 3m) (29 - 4m)

36(7 - m) (29 - 4m)

(iii) b(a + 2b) - 4(a + 2b)²

(a + 2b) {b - 4(a + 2b)}

(a + 2b) (b - 4a - 8b)

(a + 2b) (-4a - 7b)

-(a + 2b) (4a + 7b)

(v) x² - 11xy - x + 11y

x² - x - 11xy + 11y

x(x - 1) - 11y(x - 1)

(x - 11y) (x - 1)
