Answer 2

Hey!!


Question :- Factorize

$2a {}^{2} + 7ab - 15b {}^{2}$


Solution:-


$2a {}^{2} + 7ab - 15b {}^{2} \\ \\7ab \: \: as \: \: a \: difference \\ written \: \: as \\ 10ab - 3ab \\ \\ = > 2a {}^{2} + 10ab - 3ab - 15b {}^{2} \\ \\ = > 2a(a + 5b) - 3b(a + 5b) \\ \\ = > (a + 5b)(2a - 3b)$
