Answer 2

SOLUTION

TO SIMPLIFY

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

EVALUATION

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

$\sf{ = 4(5 {x}^{2} - 20xy - 3xy + 12 {y}^{2} )- (6 {x}^{2} + 9xy - 8xy - 12 {y}^{2} )}$

$\sf{ = 4(5 {x}^{2} - 23xy + 12 {y}^{2} )- (6 {x}^{2} + xy - 12 {y}^{2} )}$

$\sf{ = 20 {x}^{2} - 92xy + 48 {y}^{2} - 6 {x}^{2} - xy + 12 {y}^{2} }$

$\sf{ = 14 {x}^{2} - 93xy + 60 {y}^{2}}$
