Question

(a+b) (a-b)+(b+c) (b-c)+(c+a) (c-a) please do the sum step by step​

Answer 1

Step-by-step explanation:

(b+c)/(a-b)(a-c)+(c+a)(b-a)(b-c)+(a+b)/(c-a)(c-a)/

step 2=(b+c)/(a-b)(a-c)+(a+c)/(a-b)(b-c)+(a+b)/(a-c)(b-c)step3=[(b-c)-(a-c)+(a-c)]step 4=[b-c-a+c+a+b]/(a-b)(b-c)(a-c)step 5=(a-b)(b-c)(a-c)
