Real and rational roots
WebIf the roots of the above quadratic equation are real, equal and rational, find the value of k. Solution : The given quadratic equation is in general form. Comparing ax 2 + bx + c = 0 and 9x 2 - 6x + k = 0, a = 9, b = -6, c = k. Since the roots are real, equal and rational, the value of the discriminant 'b 2 - 4ac' must be zero. b 2 - 4ac = 0 WebThe word ‘nature’ refers to the types of numbers the roots can be — namely real, rational, irrational or imaginary. \(Δ\) is the Greek symbol for the letter D. For a quadratic function …

It is not saying that the roots = 0. A root or a zero of a polynomial are the value (s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0. 2 comments. popular nail colors for summer
