Answer:
- Given a Quadratic equation
A/Q ,we have to find the value of the K for which the given Quadratic have real and equal roots ✓
So, we can determine its value I,e the value of K by using the determinant formula which is given by
But there is a condition that the value of the will be such for that the Given Quadratic equation have roots which is real and equal ✓
_____________________________________________
So the for the real and equal roots
I,e discriminent is equal to 0✓
Let us not find the value of K which is as follows✓
now we will put the values of a,b, and c in the equation so as to get the value of K ✓
