What is the missing factor?
(n+5)()=2n2+13n+15
The missing factor is "(n+3)".
To find the missing factor, let's first simplify the equation:
(n + 5)(?) = 2n^2 + 13n + 15
Let's expand the left side of the equation using the distributive property:
n * ? + 5 * ? = 2n^2 + 13n + 15
Now we have two terms on the left side, which we can combine:
? * n + ? * 5 = 2n^2 + 13n + 15
To find the missing factor, we need to find two numbers that multiply to give 15 and add up to 13. It appears that the missing factor is 3:
3 * n + 5 * 5 = 2n^2 + 13n + 15
So, the missing factor is 3.
