Question

360=(8x*x)+6x find x

Answer 1

Solution:-

given by:-

$360 = (8x \times x) + 6x \\ 360 = 8 {x}^{2} + 6x \\ 8 {x}^{2} + 6x - 360 = 0 \\ by \: formula \\ \frac{ - {b}^{1} ( + - ) \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ \frac{ - {(6)}^{1} ( + - ) \sqrt{ {(6)}^{2} - 4 \times ( - 360) \times 8} }{2 \times 8} \\ \\ \frac{ - 6( + - ) \sqrt{36 + 11520} }{16} \\ \frac{ - 6( + - ) \sqrt{11556} }{16} \\ \frac{ - 6( + - ) 6\sqrt{321} }{16 } \\ \frac{ - 3( + - )3 \sqrt{321} }{8} \\ x = \frac{ - 3+ 3 \sqrt{321} }{8} \\ x = \frac{ - 3 - 3 \sqrt{321} }{8} \\ \\ i \: hope \: help \:$

Answer 2

$x = - \frac{3 \binom{ + }{ - } 3 \sqrt{321}}{8}$
