Explanation of Solution
Formula Used:
The roots of the
Calculation:
Substitute
Compare the equation with standard quadratic equation , a = 1 , b = -3 , c = -10.
So, the roots are :
- Case I : y = 5
Since
Compare the equation with standard quadratic equation , a = 1 , b = -3 , c = -5.
So, the roots are :
- Case II : y = -2
Since
Compare the equation with standard quadratic equation , a = 1 , b = -3 , c = 2.
So, the roots are :
So,
