5a or 4a squared
4a^2 - 5a^2 = -a^2
14a - 4a + 5a - 3a = 12a
5a - 10 = 4a + 8 is a linear equation in one variable.
4a - 5a^2
It is the same as: 9a -4a = 5a
A, 2A, 3A, 4A, 5A, and so on.
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
6-3a**2+7+4a-5a+18 3a**2-1a+31
The GCF is 4a. The equation factors into 4a(5a + 9)
21a - 6a
5a
