Factoring trinomials

6² - 6b+8

(b-4) (b-2) <- - Factored

OR

b=4

b=2 (if set to zero)

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
