It's a linear equation of the coefficient of x^2 is zero.
Think of the equation for a line. There are no x^2 terms, are there?
Consider the equation in x: (2k-3)x^2 + (k+1)x - 1 = 0. For what value of k is this a linear equation.
I don't understand what the question is asking and I'm so confused. Any help is appreciated.
