Answer:

(b-4)(b-2) <-- <em>Factored</em>

b=4

b=2 <em>(if set to zero)</em>

Step-by-step explanation:

b²-6b+8

1) Find two numbers that multiply to equal 8 and add to equal -6:

-4 and -2

2) Write them in an equation:

(b-4)(b-2)=0

3) Set both equations equal to zero:

b-4=0

b-2=0

4) Solve:

b=4

b=2

Answer:

Step-by-step explanation:

Given the sum of the series represented as $\sum\left {3} \atop {1}} \right (1.3)(0.8)^{n-1}$ . <u>To get the sum to infinity of the geometric series, we need to get its first term and its common ratio</u>. comparing to the general term of the sum of series of a GP $\sum\left {n} \atop {1}} \right (a)(r)^{n-1}$
