Question

simplify (3-√3) ^2 help me

Answer 1

Hey,

$(3 - \sqrt{3) } {}^{2} \\ \\ = (3) {}^{2} + ( \sqrt{3) {}^{2} } - 2(3)( \sqrt{3)} \\ \\ = 9 + 3 - 6 \sqrt{3} \\ \\ = 12 - 6 \sqrt{3}$

Answer 2

Hey buddy

Solve it by applying the identity of (a-b)^2 = a^2-2ab+b^2

So

3^2-2×3×√3+b^2

9-6√3+3

12-6√3

Hope it will help u
