Answer 2

Given,

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

To find,

Expansion of $(y-\sqrt{3})^{2}$.

Solution,

By applying mathematical property,

$(a - b )^{2} = (a)^{2} + (b)^{2} - 2 (a)(b) ,$

Here a = y,

b = $\sqrt{3}$.

Therefore,

$(y-\sqrt{3})^{2} = (y)^{2} + (\sqrt{3})^{2} - 2(y)( \sqrt{3})$,

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

Hence,

The Expansion of $(y-\sqrt{3})^{2} is = y^{2} +3-2\sqrt{3}y$
