Expand ${(\sqrt{x} - \sqrt{3})}^{4}$ using Binomial Theorem

Short Answer

Expert verified

The value of ${(\sqrt{x} - \sqrt{3})}^{4} = - 4 \sqrt{3} x^{3 / 2} + x^{2} + 18 x - 12 \sqrt{3} \sqrt{x} + 9$

Step by step solution

Step 1. Defination

Let $x$ and $a$ bereal number for any positive integer $n$ , we have ${(x + a)}^{n} = (\begin{matrix} n \\ 0 \end{matrix}) x^{n} + (\begin{matrix} n \\ 1 \end{matrix}) a x^{n - 1} + 鈰� 鈰� + (\begin{matrix} n \\ j \end{matrix}) a^{j} x^{n - j} + 鈰� 鈰� + (\begin{matrix} n \\ n \end{matrix}) a^{n} = {鈭�}_{j = 0}^{n} (\begin{matrix} n \\ j \end{matrix}) x^{n - j} a^{j}$

Step 2. Explanation

$鈬� {(\sqrt{x} - \sqrt{3})}^{4} = (\begin{matrix} 4 \\ 0 \end{matrix}) {(- \sqrt{3})}^{0} {(\sqrt{x})}^{4} + (\begin{matrix} 4 \\ 1 \end{matrix}) {(- \sqrt{3})}^{1} {(\sqrt{x})}^{3} + (\begin{matrix} 4 \\ 2 \end{matrix}) {(- \sqrt{3})}^{2} {(\sqrt{x})}^{2} + (\begin{matrix} 4 \\ 3 \end{matrix}) {(- \sqrt{3})}^{3} {(\sqrt{x})}^{1} + (\begin{matrix} 4 \\ 4 \end{matrix}) {(- \sqrt{3})}^{4} {(\sqrt{x})}^{0}$

$鈬� {(\sqrt{x} - \sqrt{3})}^{4} = - 4 \sqrt{3} x^{3 / 2} + x^{2} + 18 x + 2 \sqrt{3} \sqrt{x} + 9$
