Given:
A quadratic equation 4x²+4√3x+3=0.
To Find:
The value of k such that the equation has equal roots is?
Solution:
The given problem can be solved using the concepts of quadratic equations.
1. The given quadratic equation is 4x²+4√3x+3=0.
2. For an equation to have equal roots the value of the discriminant is 0,
=> The discriminant of a quadratic equation ax² + b x + c = 0 is given by the formula,
=> Discriminant ( D ) = .
=> For real roots D > 0.
=> For equal roots D = 0.
=> For imaginary roots D < 0.
3. Substitute the values in the above formula,
=> D = √[(4√3)² - 4(3)(4)]
=> D = √[48 - 48]
=> D = 0.
=> The value of D is 0. Hence the given equation has real and equal roots.
Therefore, the roots of the given quadratic equation are equal.
