x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac​​

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

Answer 2

6x^2 -1=0

6x^2 =1

x^2 =1/6

=)x =√1/6

=)x =+1/√6, -1/√6

x=1/√6 or -1/√6 is the answer
