Question

(2-3*root 2) whole square

Answer 1

Answer:

(2 – 3√2)² = 22 – 12√2 ✔✔

Step-by-step explanation:

(2 – 3√2)² = ?

We know that, (a - b)² = a² + b² - 2ab

So, by substituting in that formula, we get,

(2 – 3√2)² = (2)² + (3√2)² - 2(2)(3√2)

(2 – 3√2)² = 4 + (9×2) - 12√2

(2 – 3√2)² = 22 – 12√2

Answer 2

(2-3√2)²

Using identity : (a-b)² = a² - 2ab + b²

(2-3√2)² = (2)² - 2(2)(3√2) + (3√2)²

= 4 - 12√2 + 18

(2-3√2)² = 22-12√2 = 2(11 - 6√2)
