It is 3-6 So (x+6)(x+3) because 6*3=18 and 6+3=9
Answer:(X+3)(X+6)
Step-by-step explanation:
The factors of the expression x 2 + 9 x + 18 are ( x + 3 ) ( x + 6 ) . This is found by identifying two numbers that multiply to 18 and add to 9. Thus, the quadratic can be expressed in its factored form as ( x + 3 ) ( x + 6 ) .
