Question

Me ajude a resolver essa equação
6x elevado a 2+x-1=0

Answer 1

$Ol\acute{a},~boa~tarde!\\\\6x^2+x-1=0\\\\Coeficientes:~a=6,~b=1~e~c=-1\\\\\Delta=b^2-4ac\\\Delta=1^2-4\cdot6\cdot(-1)\\\Delta=1+24\\\Delta=25\\\\x=\dfrac{-b\pm\sqrt{\Delta}}{2a}\\\\x=\dfrac{-1\pm\sqrt{25}}{2\cdot6}\\\\x=\dfrac{-1\pm5}{12}\\\\x_1=\dfrac{-1+5}{12}=\dfrac{4}{12}=\dfrac{1}{3}\\\\x_2=\dfrac{-1-5}{12}=\dfrac{-6}{12}=-\dfrac{1}{2}\\\\\\Espero~ter~ajudado.\\Bons~estudos!~=)$
