Question

simplify: (2√8 - 3√2) square​

Answer 1

Answer:

Step-by-step explanation:

→ (2*root2^3 - 3* root2)^2

→ [2* (root 2^ *2)-3*root2]^2

→ 2

Answer 2

(2 √8 - 3 √2)²

Since (x - y)² = x² - 2xy + y²

= (2√8)² - 2(2√8)(3√2) + (3√2)²

= 4(8) - 12√16 + 9(2)

= 32 - 12√16 + 18

= 50 - 12√16

= 50 - 12(4) (Since √16 = 4)

= 50 - 48

= 2
