This is an easy trinomial. You need to find two numbers that add up to -6 and multiply together to equal 8. Those numbers are -2 and -4. It would simplify to (b-2)(b-4)
To factor the expression b 2 − 6 b + 8 , you need to find two numbers that multiply to 8 and add to -6, which are -2 and -4. This leads to the factored form ( b − 2 ) ( b − 4 ) .
