70a
12a
7...that is the LCM or least common multiple Because 7X2a=14a and 7X3=21
To factorize 14a + 21, you first need to find the greatest common factor of the two terms, which in this case is 7. You can factor out 7 from both terms to get 7(2a + 3). Therefore, the factorized form of 14a + 21 is 7(2a + 3).
negative 1
No, it is not.
a(-14-a) = 0 so a = 0 or a = -14
a=5 (14 x 5 = 70 ; 35 - 70 = -35)
Assuming the missing signs are pluses, that would work out to a^3 + 12a^2 + 14a + 5
I'm assuming you mean: 14a - 93 = 49 - 57a If so then the answer is something like this... 14a + 57a = 49 + 93 which is... -> 71a = 142 which makes a = 142/71 = 2 so : a = 2 Hope that's what you were looking for! Your welcome if it was! :)
