<u>Answer:</u>
are two roots of equation
<u>Solution:</u>
Need to solve given equation using quadratic formula.
General form of quadratic equation is
And quadratic formula for getting roots of quadratic equation is
In our case b = -1 , a = -3 and c = -3
Calculating roots of the equation we get
Since is equal to -35, which is less than zero, so given equation will not have real roots and have complex roots.
