Question

expand (2√3-3)^2
Please Help​

Answer 1

Answer:

$(2\sqrt{3} - 03)^{2}$=$(2\sqrt{3}) ^{2} +3^2+-2(2\sqrt{3} )(3)$.

Step-by-step explanation:

$(2\sqrt{3} - 03)^{2}$

using (a-b)^2=a^2+b^2-2ab,

$(2\sqrt{3} - 03)^{2}$=$(2\sqrt{3}) ^{2} +3^2+-2(2\sqrt{3} )(3)$.

Answer 2

Step-by-step explanation:

(2√3-3)²

(a - b)² = a² +b² - 2ab

(2√3)² + 3² - 2 × (2√3) ×3
