If we expand (a+b)(a-b) we will get a²-b². Factorization goes the other way: suppose we have an expression that is the difference of two squares, like x²-25 or 49x²-y², then we can factor is using the roots of those squares. For example, x²-25 can be factored as (x+5)(x-5). This is an extremely useful method that is used throughout math. Let αn be a multiple of α (this is the same step as before, just with the α times table, rather than the 3 or 5 times table). ∴ difference of squares of numbers either side is: (αn + 1)2 = α2n2 + 10n + 1 = 4αn −(αn − 1)2 −(α2n2 − 10n + 1) Dividing by α, which is the times table: 4αn α = 4n ∴ 4αn is a multiple of α.Nov 21, 2023 · The difference of two squares, or just the difference of squares, is a special case of polynomials.

This identity is often used in algebra where it is useful in applications ... 6. A difference of two squares is an expression in the form x2−y2. It expands to the expression (x+y) (x−y). When multiplying the two terms (x+y) and (x−y), the coefficient of the term with both x and y is equal to 0. That leaves us with only the x2 term and the y2 term. Here are some examples:

In this case 9 is the result of squaring 3, (32 = 9), and so 9 is a square number. Hence x2 − 9 is the difference of two squares, x2 − 32. When we try to factorise x2 − 9 we are looking for two numbers which add to zero (because there is no term in x), and which multiply to give −9. Two such numbers are −3 and 3 because.Difference of Two Squares Solving Quadratic Equations Using the Difference of Two Squares Completing the Square Quadratic Factorisation: Mixed Methods. 2-Minute Feedback Form.
