1. simplify the expression and explain each step: 4(3x+2)-2.
2. factor the expression completely: 20b - 16.

The correct answers are:

12x+6; and 4(5b-4).

Explanation:

For the first question, we first use the distributive property. It states that we multiply everything within parentheses by the term outside parentheses:

4(3x+2)-2 = 4(3x)+4(2)-2 = 12x+8-2

Combine like terms:

12x+(8-2) = 12x+6

For the second question, we first find the GCF. To do this, find the prime factorization of 20 and 16:

20 = 4*5

4 = 2*2

20 = 2*2*5

16 = 4*4

4 = 2*2

16 = 2*2*2*2

For the GCF, we take the common factors; these are 2*2 = 4. This makes 4 the GCF.

Factoring 4 out of 20b, we have 5b; factoring 4 out of -16 gives us -4. This gives us 4(5b-4).
