Question

विस्तार करा: $\bigg \lgroup \frac{1}{y} +4 \bigg \rgroup \bigg \lgroup \frac{1}{y} -9 \bigg \rgroup$

Answer 1

विस्तार करा: $\bigg \lgroup \frac{1}{y} +4 \bigg \rgroup \bigg \lgroup \frac{1}{y} -9 \bigg \rgroup$

$= \frac{1}{ {y}^{2} } - \frac{9}{y} + \frac{4}{y} - 36 \\ \\ = \frac{1}{ {y}^{2} } + \frac{ - 9 + 4}{y} - 36 \\ \\ = \frac{1}{ {y}^{2} } - \frac{5}{y} - 36$
विस्तार:

$\bigg \lgroup \frac{1}{y} +4 \bigg \rgroup \bigg \lgroup \frac{1}{y} -9 \bigg \rgroup = \frac{1}{ {y}^{2} } - \frac{5}{y} - 36$
