Step-by-step explanation:
Let
be a quadratic equation where a , b , c are coefficients and a ≠ 0.
Using quadratic formula, roots are given by![x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}](/tpl/images/0275/5351/fdf38.png)
On comparing equation
with equation
, we get ![a=3\,,\,b=-10\,,\,c=5](/tpl/images/0275/5351/79c79.png)
First , we will find
:
So,![\sqrt{b^2-4ac}=\sqrt{40}=2\sqrt{10}](/tpl/images/0275/5351/07c70.png)
Now, using quadratic formula, we will find roots of the equation .
