Katarina [22]

we are given

a^2+5a+6=0

we can use factoring formula

a^2-(m+n)a+mn=(a-m)(a-n)

we can compare

and we get

m+n=-5

mn=6

now, we can solve for m and n

and we get

m=-3 , n=-2

now, we can use formula

and we get

a^2+5a+6=(a+3)(a+2)

now, we can set it equal to 0

a^2+5a+6=(a+3)(a+2)=0

(a+3)=0

a=-3

a+2=0

a=-2

so, we will get

a=-2,a=-3.............Answer
