Question

Factorise 2a^2+13a+18

Answer 1

Hey friend, Here is your answer-
$2 {a}^{2} + 13a + 18 = 0 \\ 2 {a }^{2} + 9a + 4a + 18 = 0 \\ a(2a + 9) + 2(2a + 9) = 0 \\ (2a + 9)(a + 2) = 0 \\ 2a + 9 = 0 \: \: \: \: \: or \: \: \: \: a + 2 = 0 \\ a = \frac{ - 9}{2} \: \: \: \: \: or \: \: \: \: \: a = - 2$
