Answers to Factoring the Difference of Squares. 1) (3x + 1)(3x ? 1). 2) (2n + 7)(2n ? 7). 3) (6k + 1)(6k ? 1). 4) (p + 6)(p ? 6). 5) 2(x + 3)(x ? 3).
What we see from this is that the difference of two consecutive squares will always be an odd integer. Also since there is no limit or constraint on what n can

The di?erence of two squares x2 ?a2 always factorises to x2 ? a2 = (x? a)(x+a) Example Factorise x2 ?25 Note that x2 ?25 is the di?erence of two squares because 25 is a square number (25 = 52) So we need to factorise x2 ? 52 x2 ? 52 = (x?5)(x+5) Example Factorise y2 ? 81

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.
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.
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.
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.
