Subject: complex roots Name: Jess rutherford Who is asking: Student Level: Secondary
Question: how do I find the value of k when 5x^{2} + k = 3x and has complex roots ?
Hi Jess,
Write the equation as 5x^{2} + 3x + k = 0 and solve using the general quadratic. The roots are complex if the part under the root sign is negative.
