Answer 2

1|| $\sf{Subtract}$ 4a - 7ab + 3b + 12 from 12a - 9ab + 5b -3

$\sf{Lets \: solve ¡!}$

(12a - 9ab + 5b -3) - (4a - 7ab + 3b +12)

12a - 9ab + 5b - 3 - 4a + 7ab - 3b - 12

= $\sf{8a - 2b + 2b - 15}$ ('Answer)

____________

2|| $\sf{Multiply \: the \: binomials:}$

|A| (2x + 5) and (4x - 3)

:- (2x+5) x (4x - 3)

$\sf{2x}$ x (4x - 3) + 5x (4x - 3)

$\sf{8x^2}$ - 6x + 20x - 15

$\sf{8x^2}$ + $\sf{14x \: - 15 }$

____________

|B| (y-8) and (3y - 4)

:- (y-8) x (3y-4)

y x (3y - 4) - 8x (3y -4)

$\sf{3y^2}$ - 4y - 24y + 32

$\sf{3y^2}$ $\sf{-28y \: + 32}$
