What is the concept of 2 squared?
Understanding the concept of 2 squared is based on the origin of this problem: a square. Let’s make a square with side lengths of 2 units. In this situation, the side length represents the value being squared, and the area of the square represents the solution. This is because a square’s area is equal to the side length times itself.
How do you factor a difference of two perfect squares?
Let's put this as a formula: Factor a difference of two squares. Sometimes, the binomial is not a difference of two perfect squares, but after we factor out the GCF, the resulting binomial is a difference of two perfect squares. Then we can still use this formula to continue factoring the resulting binomial.
What is an example of difference of two squares?
An example of difference of two square is that of two values a and b which is (a+b) (a-b). From the above solution, it can be concluded that the product of complex conjugates is a difference of two squares and is always a real number.
Is the second parenthesis still a case of difference of two squares?
The second parenthesis is still a case of difference of two squares. We have no choice but to factor it out one more time. Scan through the binomials again to see if there is still a case of difference of two squares. The last binomial definitely fits the criteria.
