The correct answer is "x = -1/4" or "x = 1/2".

Step-by-step explanation:

$The \ given \ equation \ is:\\\\9x^2-(x^2+2x+1)\\\\i.e.,\\\\9x^2-x^2-2x-1\\\\8x^2-2x-1\\\\On \ factorizing \ the \ above \ equation,we \ get\\\\8x^2-4x+2x-1=0\\\\4x(2x-4)+1(2x-1)=0\\\\(4x+1)(2x-1)=0\\\\4x+1=0\\\\4x=-1\\\\x=-\frac{1}{4}\\\\Or,\\\\2x-1=0\\\\2x=1\\\\x=\frac{1}{2}$
