To expand the given expression (9x - 2y - 3z)², we can use the formula for the square of a binomial. Using this formula, the expanded form is 81x² - 36xy + 6xyz - 36xy + 4y² + 6xyz - 27z² + 12yz - 9xz.
To expand the expression (9x - 2y - 3z)2, we can use the formula for the square of a binomial. We multiply the given binomial by itself:
(9x - 2y - 3z)2 = (9x - 2y - 3z)(9x - 2y - 3z)
Using the distributive property and combining like terms, we can simplify this expression:
(9x - 2y - 3z)(9x - 2y - 3z) = (81x2 - 36xy + 6xyz - 36xy + 4y2 + 6xyz - 27z2 + 12yz - 9xz)
