$o = 3x(x - 4y) - 5x(y - 9x)$

$o = {3x}^{2} - 12xy - 5x(y - 9x)$

$o = {3x}^{2} - 12xy - 5xy + 45 {x}^{2}$

$o = {48x}^{2} - 12xy - 5xy$

$o = {48x}^{2} - 17xy$

$b = 6x(2y - 3x) - x(3y - 7x) + 4(xy - {x}^{2} )$

$b = 12xy - {18x}^{2} - 3xy + 7 {x}^{2} + 4(xy - {x}^{2} )$

$b = 12xy - {18x}^{2} - 3xy + {7x}^{2} + 4xy - {4x}^{2}$

$b = 13xy - {18x}^{2} + 7 {x}^{2} - {4x}^{2}$

$b = 13xy - {15x}^{2}$
