Question

Q-2. Solve the following.

1) If (a+b+c) (a-b+c) = (a2 +b2+c2

) than show that a/b =b/c.​

Answer 1

Answer:

Step-by-step explanation:

(a+b+c) (a-b+c) = (a2 +b2+c2)

(a+c+b)(a+c-b)=(a2 +b2+c2)

(a+c) ²-b²=(a2 +b2+c2)

a²+c²+2ac-b²=(a2 +b2+c2)

2ac-b²=b²

2ac=2b²

ac=b²

dividing both side by bc

ac/bc=b²/bc

so a/b=b/c

Hence proved
