choice a is correct answer.
given expression is :
we have to represent above expression in factored form.
as we have noticed that the expression contains the multiples of 3.
taking 3 as common from given expression,we get
now, spit the middle term of above expression so that the product of two terms should be 8 and their sum be 6.
making two groups and taking two terms as common,we get
taking (x+4) as common,we get
3(x+4)(x+2) which is the factored form of 3x²+18x+24.
