Question

prove that (x power a by x power b)(a+b-c) multiplied by (x power b by x power c)b+c-a multiplied by (x power c by x power a)c+a-b

Answer 1

Answer:

(c+a-b) (square of b -square of a -square of c+2ac)

Step-by-step explanation:

(x power a by x power b) (a+b-c) (x power b / x power c) (b+c-a) (x power c / x power a) (c+a-b)

= (a+b-c) (b+c-a) (c+a-b)

= ( square of b) - (square of a) - (square of c)+ 2ac (c+a-b)

= square of b (c+a-b) - square of a (c+a-b) - square of c (c+a-b) + 2ac (c+a-b)
