Question

-6х^2-2х-1>=0

помогите решить срочно

Answer 1

Ответ:

-6x²-2x-1>0

-6x²-2x-1=0

6x²+2x+1=0

a=6,b=2,c=1

$x = \frac{ - 2± \sqrt{2 {}^{2} - 4 \times 6 \times 1 } }{2 \times 6}$

$x = \frac{ - 2± \sqrt{2 {}^{2} - 4 \times 6 } }{2 \times 6}$

$x = \frac{ - 2± \sqrt{4 - 4 \times 6} } {2 \times 6}$

$x = \frac{ - 2± \sqrt{4 - 24} }{2 \times 6}$

$x = \frac{ - 2± \sqrt{4 - 24} }{12}$

$x = \frac{ - 2± \sqrt{ - 20} }{12}$

x∉R

-6x²-2x-1>0,a=-6
