Question

simplify (a-b+c)² - (a+b-c)²​

Answer 1

Answer:

Given:-

• (a-b+c)² - (a+b-c)²

To Do:-

• Simplify (a - b + c)² - (a + b - c)²

Identity Used:-

• a² - b² = ( a + b ) ( a - b )

Solution:-

⟾ (a - b + c)² - (a + b - c)²

⟾ (a-b+c + a+b-c) (a-b+c - a-b+c)

⟾ 2a ( c - b )

⟾ 2ac - 2ab

Hence, the required answer is 2ac - 2ab.
