Question

-4x²+2=0 (por bhaskara)

​

Answer 1

-4x^2+2=0\quad :\quad x=\sqrt{\frac{1}{2}},\:x=-\sqrt{\frac{1}{2}}\quad \left(\mathrm{Decimal}:\quad x=0.70710\dots ,\:x=-0.70710\dots \right)

-4x^2+2=0

-4x^2+2-2=0-2

-4x^2=-2

\frac{-4x^2}{-4}=\frac{-2}{-4}

x^2=\frac{1}{2}

x=\sqrt{\frac{1}{2}},\:x=-\sqrt{\frac{1}{2}}
