Question

6x2-2x=1-3x ??? mi ajudem pvf

Answer 1

$6 x^{2} -2x=1-3x$

$6 x^{2} -2x+3x-1=0$

$6 x^{2} +x-1=0$

$x= \frac{-b\pm \sqrt{b^2-4ac} }{2a}$

$x= \frac{-1\pm \sqrt{1+24} }{2.6}$

$x= \frac{-1\pm \sqrt{25} }{12}$

$x'= \frac{-1+5}{12} = \frac{4}{12} = \frac{1}{3}$

$x"= \frac{-1-5}{12} =- \frac{6}{12} =- \frac{1}{2}$

S={$- \frac{1}{2} , \frac{1}{3}$}
