(a + 2 - b) (a + 2 + b)
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
4a3 - 4a2 = 4a2*(a - 1)
a2 - 4a + 4
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
(a + 2 - b) (a + 2 + b)
5a or 4a squared
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
4a3 - 4a2 = 4a2*(a - 1)
It is -44 + 4a
5ab-2ab+4a-b+5b = 3ab+4a+4b
a2 - 4a + 4
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
4a4 + 11a3 - 47a3 - 4a + 5 =4a4 - 36a3 - 4a + 5 =4a (a3 - 9a2 - 1) + 5

4a + 3a = (4 + 3)a = 7a
10a + 3a - 4a = 9a
