Step-by-step explanation:
on comparing with general form of a quadratic equation ax^2+bx+c=0 we get the values of a, b and c.
since the roots are equal. hence dicriminant equals 0. which is b^2 - 4 ac =0
applying this condition we will get the answer

Answer:
3x²+ kx + 3 = 0
b²- 4ac = 0
k² - 4(3)3 = 0
k² - 36 = 0
k² = 36
k = √36
k = ± 6
So the value of k will be 6 or -6
Thank you ☺️✌️
