Answer 1

Hey!!


$9x(6x - 5y) - 12x {}^{2} (6x - 5y) \\ \\ factor \: \: out \: \: 3x(6x - 5y) \: \: from \\ \: \: the \: \: expression \\ \\ = > 3x(6x - 5y)(3 - 4x).$


Hope it helps!

Answer 2

∴ The solution is $3x(4x-3)(5y-6x)$

Step-by-step explanation:

Given;

$9x(6x-5y)-12x^{2} (6x-5y)$

$=54x^{2} -45xy-72x^{3} +60x^{2} y$

$=54x^{2} -72x^{3}+60x^{2} y-45xy$

$=18x^{2} (3-4x)+15xy(4x-3)$

$=-18x^{2} (4x-3)+15xy(4x-3)$

$=(4x-3)(-18x^{2} +15xy)$

$=(4x-3)3x(5y-6x)$

$=3x(4x-3)(5y-6x)$

So,the solution is $3x(4x-3)(5y-6x)$
