Question

(3-√3)² simplify it by using identity
(a-b)²=a²-2ab+b²
help me out...​
plz plz fast...fast....​

Answer 1

Step-by-step explanation:

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.
