Given expression
(2√2 - 5)² + (3√2 + √3)² - (√2 - 1)²
Solving (2√2 - 5)²
Here, we use the formula,
♣ (a - b)² = a² - 2ab + b²
According to the formula
_________________________________________
Solving (3√2 + √3)²
Here, we use the formula,
♣ (a + b)² = a² + 2ab + b²
___________________________________________
Solving (√2 - 1)²
Here also we the formula,
♣ (a - b)² = a² - 2ab + b²
Now,
We have,
(2√2 - 5)² = -20√2 + 29
(3√2 + √3)² = 6√6 + 9
(√2 - 1)² = - 2√2 + 3
We have to find,
(2√2 - 5)² + (3√2 + √3)² - (√2 - 1)²
