Question

Simplify this expression and show each step.

4(3x + 2) -2

Factor the expression completely
20b - 16

Answer 1

`4(3x+2)-2` Expression


`12x+8-2` Distribute the 4 into the parenthesis


`12x+6` Simplify



`20b-16` Expression


`4(5b-4)` Take out GCF of 4


`5b-4=0` Set up equal to 0


`5b=4` Add 4 to both sides


`b= (4)/(5)` Divide by 5 on both sides

Answer 2

Simplify this expression and show each step.
4(3x + 2) -2
= 12x + 8 - 2
= 12x + 6

Factor the expression completely
20b - 16
= 4(5b - 4)
