Answer 2

Answer:

We Have

${x}^{2} + x = 40$

Which Implies

${x}^{2} + x - 40 = 0$

$x = \frac{ - 1 + \sqrt{1 - 4( - 40)} }{2} \: \: or \: \: \\ x = \frac{ - 1 - \sqrt{1 - 4( - 40)} }{2}$

Implies

$x = \frac{ - 1 + \sqrt{161} }{2}$

$or \: \: x = \frac{ - 1 - \sqrt{161} }{2}$

Imlies

$x = \frac{ - 1 + 12.689}{2}$

$or \: \: x = \frac{ - 1 - 12.689}{2}$

Implies

$x = 5.8445$

$or \: \: x = - 6.8445$
