Question

(a+b+c)² - (a-b+c)² simplify​

Answer 1

Answer:

4(ab+bc)

Step-by-step explanation:

a+b+c)²=a²+b²+c²+2ab+2bc+2ca

Answer 2

By using the formula of

a^2 - b ^2 = (a+b)(a-b)

We can write this equation as

=(a+b+c+a−b+c){a+b+c−(a−b+c)}

=(2a+2c)(a+b+c−a+b−c)

=(2a+2c)(2b)

=4ab+4bc

=4b(a+c)
