The equation 2x2 + ax + b = 0 has only one solution. Given that a ≠ 0 and am = kb, then the relationship between k and m is
Question
Solution 1
The equation 2x^2 + ax + b = 0 has only one solution. This means that the discriminant of the quadratic equation, which is given by a^2 - 4*b, must be equal to zero (since the discriminant gives the number of solutions of a quadratic equation).
So, we have:
a^2 - 4*b = 0
