Factorise by taking out the commmon factors : 1) ab(a²+b²-c²) – bc(c²-a²-b²) + ca(a²+b²-c²).

Question

Factorise by taking out the commmon factors :                        1) ab(a²+b²-c²) - bc(c²-a²-b²) + ca(a²+b²-c²).​

Skylar · Answer

Answer:   ab(a²+b²-c²) -bc(c²-a²-b²) +ca(a²+b²-c²)      ab(a²+b²-c²) +bc(-c²+a²+b²) +ca(a²+b²-c²)      ab(a²+b²-c²) +bc(a²+b²-c²) +ca(a²+b²-c²)      (a²+b²-c²)(ab+bc+ca)      Or,      ===========================      {a+(b-c)(b+c)} [ab +bc+ca]

Show that the line segments joining the mid-points of the opposite sides of a quadrilateral bisect each other

Evaluate \dfrac {15}k
k
15

start fraction, 15, divided by, k, end fraction when k=3k=3k, equals, 3
