Solving the equation using quadratic formula we get![\mathbf{x=0.119\:or\:x=-2.785}](/tpl/images/1083/0447/d3d2e.png)
Step-by-step explanation:
We need to use the quadratic formula to find the solutions for
(Note: quadratic formula is used when x^2 is in the equation. So considering 3x^2 instead of 3x^3)
The quadratic formula is:![x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}](/tpl/images/1083/0447/77630.png)
From the given equation
we have a =3, b=8 and c =-1
Putting values in the formula and finding solutions:
So, Solving the equation using quadratic formula we get![\mathbf{x=0.119\:or\:x=-2.785}](/tpl/images/1083/0447/d3d2e.png)
