Solve 4x |
| Answer» The given equation is 4x2 - 4x + 1 = 0Here a = 4, b = - 4, c= 1{tex}\\therefore D=b^2-4ac = (-4)^2-4(4)(1) = 16-16=0{/tex}So, the given equation has equal roots{tex}x = {-b \\pm \\sqrt{D} \\over 2a} = {-(-4) \\pm0 \\over 2(4)}{/tex}{tex}\\implies x={4 \\over 8}= {1 \\over2}{/tex}{tex}Hence,\\, x={1 \\over 2}, \\,{1 \\over 2}{/tex}are the required roots. | |
