Hey Mate!!

$4 {a}^{2} + 24a + 36 \\ = > 4( {a}^{2} + 6a + 9) \\ = > 4( {a}^{2} + 3a + 3a + 9) \\ = > 4(a(a + 3) + 3(a + 3)) \\ = > 4((a + 3)(a + 3)) \\ = > 4 {(a + 3)}^{2}$

Answer 2

Answer:

a= -3 , -3.

Step-by-step explanation:

4a^2+24a+36

4a^2+12a+12a+36=0

4a(a+3) +12(a+3)=0

(4a+12) (a+3)=0

4a+12=0 or a+3=0

a=-12/4 or a=-3

Therefore, a=-3 or -3
