Step-by-step explanation:
Bringing like terms on one side
a2 - 2 = - 8a + 7a
a2 - 2 = - a
a2 + a - 2
a2 +2a - a - 2
a(a + 2) - 1 (a + 2)
(a + 2) and (a - 1)are the factors
Answer:
Option 3,5 are under first expression and Option 1,2 are under second expression.

Answer:
Step-by-step explanation:
Let X be the no of defective components produced by a certain process in one day
X is Poisson with parameter = 20
Y = no of components that can be repaired
Since each component to be repaired is independent of the other Y is Binomial with p =0.60
a) 
b) P(Y = 10)= Binomial prob (15,0.6) for y =10
= 
Here no of repairables X is binomial.
c) Prob for 15 produced and 10 repairable = product of a and b
= 0.009603
