Question 122680
{{{( (2x) / (2x - 2) )^-2}}} Start with the given expression




{{{( (2x - 2) /(2x)  )^2}}} Flip the fraction and rewrite with a positive exponent




{{{ (2x - 2)^2 /(2x)^2  }}} Distribute the exponent



{{{ (4x^2-8x+4) /(2x)^2  }}} Foil



{{{ (4x^2-8x+4) /(4x^2)  }}} Square {{{2x}}} to get {{{4x^2}}}
