Answer:wrfeewdfwesd
at least 51,569 blocks ( same as 51569)
973 * 53
I think it is 14
f(-7)
-7(a)=7a
-7a=7a
+7
a= 14
12a³ + 12a² = -3a | + 3a
12a³ + 12a² + 3a = 0
3a(4a² + 4a + 1) = 0
3a(2a + 1)² = 0
3a = 0 or (2a + 1)² = 0
1) 3a = 0 | : 3
a = 0
2) (2a + 1)² = 0
2a + 1 = 0 | - 1
2a = -1 | : 2
a = -1/2
a ∈ {-1/2, 0}
Used formula:
(a + b)² = a² + 2ab + b²
