EXPLANATION.
Factorizes.
⇒ 9x(6x - 5y) - 12x²(6x - 5y).
As we know that,
We can write equation as,
⇒ 54x² - 45xy - [72x³ - 60x²y].
⇒ 54x² - 45xy - 72x³ + 60x²y.
⇒ x[54x - 45y - 72x² + 60xy].

(1) = (x + y)² = x² + y² + 2xy.
(2) = (x - y)² = x² + y² - 2xy.
(3) = (x² + y²) = (x + y)² - 2xy.
(4) = (x² - y²) = (x + y)(x - y).
(5) = (x³ - y³) = (x - y)(x² + xy + y²).
(6) = (x³ + y³) = (x + y)(x² - xy + y²).
(7) = (x + y)³ = x³ + 3x²y + 3xy² + y³.
(8) = (x - y)³ = x³ - 3x²y + 3xy² - y³.
