a2-b2=(a-b)(a b) conditions

I couldn’t figure out how to add a comment to Viktor T. Toth’s nice answer. So I am providing a comment here. Viktor’s analysis shows we find that [math]B^{-1}A-AB^{-1}=2I[/math]. I am not a good enough mathematician to characterize all

a² – b² = (a+b)(a-b) Here a and b are the real numbers. (a+b)(a-b) =a(a-b)+b(a-b) [Addition Distributive Law] =a²-ab+ba-b² [Addition Distributive Law] =a²-ab+ab

IF 函數可讓您測試條件並將條件為 True 或 False 的結果傳回,藉以在值與預期值之間進行邏輯比較。 =IF(項目為 True,則執行某項目,反之則執行其他項目) 但如果您需要測試多個條件,可以假設所有條件都必須為 True 或 False (AND),或只有一個條件必須為 True

Question: to simplify(a 2-b 2) 3 +(b 2-c 2) 3 +(c 2-a 2) 3 / (a-b) 3 +(b-c) 3 +(c-a) 3 Answer: Let’s solve the numerator first. if a+b+c = 0 Then a 3 +b 3 +c 3 = 3abc Now,(a 2-b 2) 3 +(b 2-c 2) 3 +(c 2-a 2) 3 = a 2-b 2 +b 2-c 2 +c 2-a 2 = 0 That means we can use this

By looking at the question, I guess you are stuck as you probably don’t know some basics required to solve this question, as the question clearly doesn’t require any deep thinking. So let’s start from the beginning. Assumptions: 1. A2, B2 and

Difference of Two Perfect Squares a2 is perfect square b2 is perfect square a2 – b2 Minus Sign (difference) Factoring the Difference of Two Perfect Squares a2 – b2 = (a + b)( a – b) Factor the Difference of Two Perfect Squares a2 – b2 = (a + b

a+b = b –we divide both side by (a-b) b+b = b –since a = b, we can substitute b for a 2b = b –combine like terms b+b and get 2b 2 = 1 –we divide both sides by b The fallacy is in the step colored red.
