Answer:
Explanation:
what two numbers can you multiply that will equal to 30 when you multiply but 13 when you add them?
10+3=13 10*3=30
so we can use 10 and 3
since the first symbol (x^2+13x) is positive than the bigger number you got earlier (10) will be positive
(x+10)
since the second symbol (13x+30) is positive than our next symbol will be positive as well
(x+3)
combine them so now they are (x+10)(x+3)
