Textbook Problem

In Exercises 1 to 6, simplify by combining similar terms. x + ( 3 x + 2 ) − ( 2 x + 4 )

To determine

To simplify:

x+(3x+2)(2x+4)

Explanation

Forms of the Distributive Axiom:

The Distributive Axiom distributes multiplication over addition:

a(b+c)=ab+acab+ac=a(b+c)

The Distributive Axiom distributes multiplication over subtraction:

a(bc)=abacabac=a(bc)

Calculation:

Given: x+(3x+2)(2x+4)

Now we have to simplify by combining similar terms.

Remove parentheses: (a)=aDistribute parentheses: (2x+4)=(
