Answer 1

☁️Hola☁️

${x}^{2} + x = 35 \\ {x}^{2} + x - 35 = 0 \\ x = \frac{ - 1 + \sqrt{141} }{2} \\ \frac{ - 1 - \sqrt{141} }{2}$

Hecho ✔️

Decimal form: 5,437171, -6,437171.

Answer 2

${x}^{2} + x = 35 \\ {x}^{2} + x - 35 = 0 \\ a = 1. \\ b = 1. \\ c = - 35. \\ x = \frac{ - 1 + - \sqrt{ {1}^{2} - 4 \times 1 \times ( - 35)} }{2 \times 1} \\ x = \frac{ - 1 + - \sqrt{1 + 140} }{2} \\ x = \frac{ - 1 + - \sqrt{141} }{2} \\ \bf \: x = \frac{ - 1 + \sqrt{141} }{2} \\ \bf \: x = \frac{ - 1 - \sqrt{141} }{2}$
