1 + .3 +.07+.005 x 10 - 6
Answer:
The answer is -2
Step-by-step explanation:
-6 + 4 = -2
Since anything multiplied by zero produces zero, we can say 0(a + 1) = 0 and (2a - 2)(0) = 0.
Thus, 2a - 2 = 0 or a + 1 = 0
2a = 2
a = 1
a = -1
We can conclude that a = 1 or - 1 will produce the end result as 0.
