Factoring To Reduc Fractions - 2
Once the LCD is found rewrite each fraction in terms of the LCD—multiply each fraction by the ‘‘missing’’ factors over themselves. Then add or subtract the numerators.
Factoring To Reduc Fractions - 1
Before adding or subtracting fractions factor the denominator. Once the denominator is factored you can determine the LCD.

Factoring To Reduce Fractions
To reduce a fraction to its lowest terms, factor the numerator and denominator. Cancel any like factors.
Factoring Quadratic Polynomials - 6
The coefficient of the x2 term will not always factor away. In
order to factor quadratics such as 4x2 + 8x + 3 you will need to try
all combinations of factors of 4 and of 3: 
. The blanks will be filled in with the factors of 3. You will need to
check all of th possibilities:

Factoring Quadratic Polynomials - 4
The difference of two squares can come in the form xn – cn where n is any even number. The factorization is xn – cn = (xn/2 – cn/2)(xn/2 + xn/2). [When n is odd, xn – cn can be factored also but this factorization will not be covered here.]
