Category: Algebra

"Published in Suisun City, California, USA"

Simplify


Solution:

Consider the given equation above


The common factor of the numerator is (x - 1)². 1 and x² at the denominator can be interchanged as follows





The denominator is a perfect trinomial square. Therefore, after cross out their Greatest Common Factor (GCF) and simplify into lowest term, the final answer is

Simplifying Algebraic Fractions, 6

Category: Algebra

"Published in Suisun City, California, USA"

Simplify


Solution:

Consider the give equation above


After the inspection of the terms, the numerator can be factored by the difference of two cubes and the denominator can be factored by the difference of two squares as follows



Change the sign of the term at the denominator which is (2 - y) into - (y - 2) as follows



The greatest common factor (GCF) of the numerator and denominator is (y - 2). Cross out their GCF and simplify into lowest term. Therefore, the final answer is

Simplifying Algebraic Fractions, 5

Category: Algebra

"Published in Suisun City, California, USA"

 Simplify


Solution:

Consider the given equation above


The first thing that we have to do is to inspect all the terms at the numerator and denominator. Let's group the first two terms at the numerator and then the next two terms at the numerator also, as follows



The first group can be factored by the difference of two squares while the other group can be factored by removal of their common factor, as follows



The common factor at the numerator is (x + y). Remove their common factor, we have



The greatest common factor (GCF) of the numerator and denominator is (x - y + 2). Cross out their GCF and simplify into lowest term. Therefore, the final answer is
