Question

Find each of the following products-----. (x-3/x) (x-3/x)​

Answer 1

Answer:

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

$\frac{ {x}^{4} + 9 - 6 {x}^{2} }{ {x}^{2} } = 0$

$\frac{ {x}^{4} - {6x }^{2} + 9}{ {x}^{2} } = \frac{ {x}^{2} ( {x}^{2} - 6) + 9 }{ {x}^{2} } = {x}^{2} - 6 + 9 = 0$

${x}^{2} = - 3$

that's is your answer
