Question

(1/2x-3/2y)^2 plese write in standard form​

Answer 1

Step-by-step explanation:

$\star \fbox{\underline{\underline{\bold{Answer :}}}}$

$\star \: \fbox {\fbox{\underline{\underline{\orange{given : }}}}}$

$\Longrightarrow \: \bigg( \frac{1}{2x} - \frac{3}{2y} \bigg) {}^{2} \\ \Longrightarrow \: \bigg[ \bigg(\frac{1}{2x} \bigg) {}^{2} + \bigg( \frac{3}{2y} \bigg) {}^{2} - 2 \times \frac{1}{2x} + \frac{3}{2y} \bigg] \\ \Longrightarrow \: \bigg( \frac{1}{4x {}^{2} } + \frac{9}{4y {}^{2} } - \frac{3}{2xy} \bigg)$

= SOME IMPORTANT POINTS RELATED TO THIS QUESTION:-

a) YOU MUST KNOW ALL IMPORTANT ALGEBRAIC FORMULAES TO SOLVE THESE TYPE OF QUESTIONS EASILY LIKES :-

$\star(a + b) {}^{2} = a {}^{2} + 2ab + b {}^{2}. \\ \star \: (a - b) {}^{2} = a {}^{2} - 2ab + b {}^{2}. \\ \star \: (a {}^{2} - b {}^{2} ) = (a + b) \times (a - b).$

b) PRECISE CALCULATION IS MUST.

C) IN THESE TYPE OF QUESTIONS BRACKETS PLAYS AN IMPORTANT ROLES.
