please answer me fast ​

Answer 1

Answer:

Step-by-step explanation:

(a+3) (a+6)

identity:(x+a) (x+b)=x²( a+b)x+ab

(a+3) (a+6) =(a)²+(3+6)a+(6)(3)

                 =  a²+9(a)+18

                    =a²+9a+18

hope it is useful

               

Answer 2

The identity that should be used is " (x + a) (x+ b)= x² + (a+b)x + ab "

(a+3) (a+6)

a²+(3+6)a +(3×6)

a²+9a+18 is the answer.
