we have,

• (2p - 6q)²

use the identity

• (a - b)² = a² + b² - 2ab

$\implies {(2p - 6q)}^{2} = {(2p)}^{2} + {(6q)}^{2} - 2 \times 2p \times 6q \\ \\ \implies \boxed{4p^{2} + {36q}^{2} - 24pq} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

so the product is 4p² + 36q² - 24pq
