Answer 2

${x}^{2} - 328 x+ 1280 = 0 \\ \frac{ - b \frac{ + }{ - } \sqrt{ {b}^{2} - 4ac } }{2a} \\ \frac{328 \frac{ + }{ - } \sqrt{ {328}^{2} - 4 \times 1 \times 1280} }{2 \times 1} \\ \frac{328 \frac{ + }{ - } \sqrt{107584 } - 5120 }{2} \\ \frac{328 \frac{ + }{ - } \sqrt{102464} }{2} \\ \frac{328 \frac{ + }{ - } 320.09}{2} \\ put \: on \: plus \\ \frac{328 + 320.09}{2} \\ \frac{648.09}{2} \\ (324.045) = x \\ put \: on \: minus \\ \frac{328 - 320.09}{2} \\ \frac{7.91}{2} \\ (3.95) = x$
