Enrico Gregorio Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Therefore: a^2 - b^2 = ab - b^2 Therefore: (a + b)(a - b) = b(a - b) Now divide both sides by (a - b) Therefore: a + b = b But since a = b and substituting b for a Therefore: b + b = b Therefore: 2b = b Now divide both sides by b Therefore: 2 = 1 QED This doesn't work because in line 5 both sides of the equation are divided by (a-b). a+b)^2 = a^2 + 2(a.b) + b^2: (a+b)^2 = (a+b). if AB is a two digit number then AB^2 does not mean A^2 x B^2, or A x B^2.

If a group G is Abelian, then for any two elements a and b, a*b = b*a Now, Define c=a*b which is also a member of G on virtue of closure property. (a+b)2 = a2 + 2(a)(b) + b2 Reemplazamos los datos: (5)2 = a2 + 2(3) + b2 25 = a2 + 6 + b2 \ a2 + b2 = 19 2. Function 'scanf' returns number of succesfully matched items. 1, the law of cosines states = + − ⁡, where γ denotes the angle contained between sides of lengths a and b and opposite the side of length c. La respuesta que tu obtuviste es correcta, el problema es que te faltó operar los términos de "ab", fíjate que en tu resultado te quedo -ab+ab, lo cual si lo operamos da cero, por lo tanto el resultado quedaría tal y como te lo dio tu maestra, ósea a^2-b^2. a^2 +2ab+b^2 porque ab=ba, pero esta igualdad es dificilmente cierta cuando se trata de matrices. 19th May, 2014.
