Question

How do you solve `-6x^2-9x+2=0` using the quadratic formula?

Answer 1

x=-1.696484724
or
x=0.1964847243

Explanation:

`x={-(-9)\pmsqrt[9^2-(4xx(-6)xx2)]}/(2xx(-6))`

`x={9\pmsqrt[81+48]}/(-12)`

`x={9\pmsqrt[129]}/(-12)`

`x={9+sqrt[129]}/(-12)` `=> x=-1.696484724`

or

`x={9-sqrt[129]}/(-12)` `=> x=0.1964847243`
