The answer is (x+3)(x+5)
There are two x’s so therefor you break down x^2 ( don’t forget your “()” )
The plus sign in front of the 15 tells you that the operations of both number will be positive and the plus in front of the 8x tells you that the biggest number will be positive.
Now you say to yourself what two numbers times to go into 15 and 3 and 5 goes into it perfectly.
