Question

${a}^{2} + 5a + 6$

Answer 1

Hello Friend

Here is your answer below,

$a {}^{2} + 5a + 6 \\ = > a {}^{2} + 3a + 2a + 6 = 0 \\ = > a(a + 3) + 2(a + 3) = 0\\ = > (a + 3)(a + 2) = 0 \\ = > a + 3 = 0 \\ = > a = - 3 \\ or \\ = > a + 2 = 0 \\ = > a = - 2$

I hope that helps you,

$\huge\sf\underline{♡Solution♡}$

${a}^{2} + 5a + 6$
$= {a}^{2} + (3 +2)a + 6$
$= {a}^{2} + 3a +2a + 6$
$= a(a + 3) +2(a +3)$
$= (a+2)(a+3)$

Hope it's right.....
