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

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
