Question

помогите решить уравнение пожалуйста

x-6/x=-1

Answer 1

$\mathtt{\huge{x - \frac{6}{x} = - 1}} \\ \\ \mathtt{\huge{x - \frac{6}{x} + 1 = 0}} \\ \\ \mathtt{\huge{ \frac{x ^{2} - 6 + x}{x} = 0}} \\ \\ \mathtt{\huge{x ^{2} - 6 + x = 0}} \\ \\ \mathtt{\huge{x ^{2} + x - 6 = 0 }}$

D=1²-4*1*(-6)=1+24=25

$\mathtt{\huge{x1 = \frac{ - 1 + \sqrt{25} }{2 \times 1} = \frac{ - 1 + 5}{2} = \frac{4}{2} = 2 }} \\ \mathtt{\huge{x2 = \frac{ - 1 - \sqrt{25} }{2 \times 1} = \frac{ - 1 - 5}{2 \times 1} = \frac{ - 6}{2} = - 3 }} \\ \mathtt{\Huge{\boxed{otvet:~x1 = 2~~~~~~~~~x2 = - 3~~~~~}}}$
