Answer 1

$(3x - \frac{5}{2} ) ^{2}$

Identity:- (a-b)² = a²+b²-2ab

$( {3x})^{2} + ( \frac{5}{2} )^{2} - 2(3x)( \frac{5}{2} ) = 0$

$9x^{2} + \frac{25}{4} - \frac{30x}{2} = 0$

$9x^{2} + \frac{25 - 60x}{4} = 0$

$\frac{36x ^{2} + 25 - 60x}{4} = 0$

$36x ^{2} + 25 - 60x = 0$

I hope this will help you friend.
