In the quadratic equation kx2-6x-1 0
WebAnswer (1 of 2): kx²-2kx+6 = 0 has equal roots => b² = 4ac => 4k² = 4*6*k => k² = 6k => k(k-6) = 0 -> k = 0 or k = 6. But as the condition of quadratic equation ax²+bx+c=0 says that it is a quadratic equation if and only if a not = 0. Therefore k = 0 is not one of the answers. The answer is k... WebFor what values of k, the equation `kx^(2)-6x-2=0` has real roots?

WebHere is our second quadratic equation. 3𝑥 2 − 6𝑥 + 3 = 0. When we calculate its discriminant, we see that it equals zero. D = 36 – 36 = 0 Thus, there is a single solution to this equation. By applying the formula with D equals zero, we get: b x= - 2a −6 6 =− = =1 2∗3 6. Finally, here is our third equation: 𝑥2 − 𝑥 + 3 = 0 WebFor what value S of a quadratic equation 30 AX² 6x 1 0 has no real roots?
