Question

(a+b)²+(a-b)² give me the answer​

Answer 1

Answer:

As you (should have) learned in algebra class:

(a+b)² = a² + 2ab + b² and (a-b)² = a² - 2ab + b².

Therefore (a+b)² - (a-b)² = (a² + 2ab + b²) - (a² - 2ab + b²).

Regrouping, we have (a+b)² - (a-b)² = (a²-a²) + (2ab-(-2ab)) + (b²-b²), which simplifies to 4ab.

Answer 2

Answer:

(a+b)*2+(a-b)*2

a*2+2ab+b*2 +a*2-2ab+b*2

2a*2+2b*2 is ans
