Factor 2a+13a-7
well, obviously you can factor out the a:
a(2+13) - 7
That's just 15a-7, which you could have achieved just by adding 2a+13a=15a, so I don't see much point in factoring it. Creepy example.
2a+13-7 IDK
To factor the expression 2a + 13a - 7, we need to look for common factors among the terms. In this case, we can see that both terms contain the variable 'a'. We can factor out the common factor 'a' from both terms:
2a + 13a - 7
Taking out the common factor 'a', we get:
a(2 + 13) - 7
Simplifying further:
a(15) - 7
Now, the expression is factored as:
15a - 7
