$\green\leadsto \sf{(6a + 5b)(7a - 3ab)}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\leadsto\sf \green{Solution:-}$

$\green\leadsto \sf{(6a + 5b)(7a - 3ab)}$

$\green\leadsto \sf{6a(7a - 3ab) + 5b(7a - 3ab)}$

$\leadsto \sf \green{ {42a}^{2} - 18 {a}^{2}b + 35ab \: - 15a {b}^{2} }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\green\leadsto\sf{Steps \: to \: solve \: this \: ques\downarrow}$

$\leadsto\sf \green{Multiply \: 6a × 7a - 3ab \: and \: 5b × 7a - 3ab}$

$\leadsto\sf\green{Use \: + \: sign \: in \: between \: because \: 5b \: is \: positive}$
