![]() They’re looking to come back from behind in this game. ![]() Now let’s join them in the bonus round already in progress. At last, just simplify the expressions and the equation is factored. Plug in the square root of the first term, x², in the first place in the parentheses and the root of the second term - disregard the minus sign - in the second place. Next, complete the parentheses with the square roots of the two terms from the binomial. ![]() Let’s see how they did it: First, set up your two factors like this: ( + )( - ) = 0. They were asked to solve x 2 - 64 = 0, which is the difference of two squares. They’re correct and get the square! And Round 1 goes to Phillip & Lara! Let’s take another look at the game-winning question. Evil says the answer is (x + 8)(x -8) = 0 and Phillip and Lara agree. Evil, the question is: How do you factor x 2 - 64 = 0? Dr. It’s time to play “The Difference of Two Squares”! Okay, it’s Phillip and Lara’s turn and they choose Dr. Welcome back! Let’s join our game, already in progress. Solve quadratic equations in one variable. Product of Sum and Difference of Two Squares: (a + b)( a – b) = a² – b²įactors of Difference of Two Squares: a² – b² = (a + b)(a – b) This method for factoring the difference of two squares can be represented in algebraic expressions as follows: To know more about this method for factoring the difference of two squares, you can watch this video. In other words, the factorization of 4x² – 25 = 0 is (2x + 5)(2x – 5) = 0, or (2x – 5)(2x + 5) = 0, as the commutative property of real numbers states that order of factors in multiplication or addition does not matter. Then 2x and 5 are the terms which appear in our product. When factoring such a difference of two squares, we end up always getting the product of the sum and the difference of the same two terms.įor instance, with 4x² – 25 = 0, we end up taking the square roots of 4x² and 25 to get 2x and 5, respectively. If you choose to write your mathematical statements, here is a list of acceptable math symbols and operators.We will learn on how to factor the difference of two squares.
