<h3><u>Correct Questions :- </u></h3>
Find the values of P for which the quadratic equation 4x²+px+3=0 , provided that roots are equal or discriminant is zero .
<h3><u>Solution</u>:- </h3>Let us Consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
For equal roots
- D = 0
So,
Here,
- α = 4
- β = p
- c = 3
Now,
Thus, the values of P for which the quadratic equation 4x²+px+3=0 are-
4√3 and -4√3.
