\mathsf{4a^2 - 9b^2 - 2a - 3b}

\fbox{\mathsf{On\:squaring\:the\:first\:two\: terms}}

\mathsf{(2a)^2 - (3b)^2 - 2a - 3b}

\fbox{\mathsf{Using: \: a^2 - b^2 \: = (a+b) (a-b)}}

\mathsf{(2a + 3b) (2a - 3b) - (2a + 3b)}

\fbox{\mathsf{Taking: \: (2a + 3b) \: as\:common}}

\mathsf{(2a + 3b) [(2a - 3b) - 1]}

\mathsf{(2a + 3b) (2a - 3b - 1)}

Solution: (2a + 3b) (2a - 3b - 1)
