Where the B2 also pales in comparison to the C2 is ... Basic Math. Solve for b a^2+b^2=c^2. a2 + b2 = c2 a 2 + b 2 = c 2. Subtract a2 a 2 from both sides of the equation. b2 = c2 −a2 b 2 = c 2 - a 2. Take the specified root of both sides of the equation to eliminate the exponent on the left side. b = ±√c2 − a2 b = ± c 2 - a 2. In mathematical terms it's: A2+ B2= C2. The hypotenuse of a right angled triangle is the longest side, or the one opposite the right angle. It can be calculated using a variety of methods - Pythagoras theorem : A2 + B2 = C2, where A and B are the sides adjacent to the right angle, and C is the hypotenuse.The LG C2 range not only comes in more sizes – with a 42-inch, 48-inch and gargantuan 83-inch model in addition to the sizes of the LG B2 – but is only marginally more expensive. The 42-inch ...2. 2. - ab - bc - ca as Sum of Squares. Here we will express a2 2 + b2 2 + c2 2 – ab – bc – ca as sum of squares. a2 2 + b2 2 + c2 2 – ab – bc – ca = 12 1 2 {2a2 2 + 2b2 2 + 2c2 2 – 2ab – 2bc – 2ca} = 12 1 2 { (a2 2 + b2 2 – 2ab) + (b2 2 + c2 2 – 2bc) + (c2 2 + a2 2 – 2ca)} = 12 1 2 { (a - b)2 2 + (b - c)2 2 + (c – a)2 2 } If a+b+c = 0 and a2 +b2 +c2 = ab+bc+ac, then it follows that 0 = (a+b+c)2 = a2 +b2 +c2 +2(ab+bc+ac), or a2 +b2 +c2 = −2(ab+bc+ac). Put this together and we will see that in fact a2 +b2 +c2 = 0, ... There is an important principle in algebra, that the order of operations must be observed.
