A quadratic equation that has 2 roots that are equal means that the discriminant of the equation is 0. The value of k that makes the equation have 2 real and equal roots is
Given that:
Rewrite as:
A quadratic equation is represented as:
By comparison:
If an equation has 2 real and equal roots, then:
So, we have:
Divide by 4
Divide by 6
Subtract 2 from both sides
Take LCM
Divide by 2
Hence, the value of k that makes the equation have 2 real and equal roots is
