Question

expand
(2/3x-3/2x-1)^2

Answer 1

Answer:

This is the answer 4/6x2-9x-3

Answer 2

$(\frac{2}{3x} - \frac{3}{2x} -1)^2$ $=\frac{61}{x^2} +\frac{5}{3x} +1$

Step-by-step explanation:

Given,

$(\frac{2}{3x} - \frac{3}{2x} -1)^2$

$=(\frac{2}{3x} )^2+(\frac{3}{2x})^2+1^2+2.( \frac{2}{3x}).(-1)+2.(-\frac{3}{2x}).(-1)+2.( \frac{2}{3x})(-\frac{3}{2x})$

$=\frac{4}{9x^2} +\frac{9}{4x^2} +1-\frac{4}{3x} +\frac{3}{x} -\frac{2}{x^2}$

$=\frac{61}{x^2} +\frac{5}{3x} +1$

The given expression is one variable expression.

There is only one variable and that is x.

Variable: Variable is an unknown quantity whose the value of variable can be changes.
