We need to add fractions.

The following rule is applied:

AB+CD=LCDBA+LCDDCLCD

This example involves 2 terms.

Note that 1 non-fractional terms are treated as fractions with denominator equal to 1.

The LCD is equal to:

Number 1 as a factor, does not need to be explicitly written.

In other words: 1A=A.

In our example, the above transformation has been applied once.

We need to get rid of parentheses in this term.

All the negative factors will change sign.

In our example, we do not have any negative factors.

The sign of the term will not change.

Numerical terms are commonly written first.

We need to get rid of expression parentheses.

If there is a negative sign in front of it, each term within the expression changes sign.

Otherwise, the expression remains unchanged.

Simple numerical terms are commonly written last.

We need to arrange this term for expansion.

Commonly, the non-expandable factor is written first.

In our example, the factor is 8x.

We need to expand this term by multiplying a term and an expression.

The following product distributive property will be used:

A(B+C)=AB+AC.

We need to combine like factors in this term by adding up all the exponents and copying the base.

No exponent implies the value of 1.

Number 1 as a factor, does not need to be explicitly written.

In other words: 1A=A.

In our example, the above transformation has been applied once.

Numerical terms in this expression have been added.

We need to get rid of expression parentheses.

If there is a negative sign in front of it, each term within the expression changes sign.

Otherwise, the expression remains unchanged.

We need to organize this expression into groups of like terms, so we can combine them easier.

We need to combine like terms in this expression by adding up all numerical coefficients and copying the literal part, if any.

No numerical coefficient implies value of 1.
