Make the given expression in terms of α + β and αβ — task. Maths CBSE Live product, Class 10.

Write each of the following expression in terms of \(\alpha + \beta\) and \(\alpha \beta\).

1.

\frac{β}{2 α} + \frac{α}{2 β}

\(=\)

$\frac{{(α + β)}^{2} - 2 α β}{α β}$
$\frac{{(α + β)}^{2} + 2 α β}{2 α β}$
$\frac{{(α + β)}^{2} - 2 α β}{2 α β}$
$\frac{{(α + β)}^{2} + 2 α β}{4 α β}$

2.

\frac{β^{2}}{5 α} + \frac{α^{2}}{5 β}

\(=\)

$\frac{{(α + β)}^{3} + 3 α β (α + β)}{5 α β}$
$\frac{{(α + β)}^{3} - 3 α β (α + β)}{5 α β}$
$\frac{{(α + β)}^{3} + 3 α β (α + β)}{5 {(α β)}^{2}}$
$\frac{{(α + β)}^{2} - 3 α β (α + β)}{5 α β}$
