**Use the discriminant to find the range of values of k**

Discriminant Figure 3. Discriminant signs and the y-coordinate of the vertex may be found by substituting this x-value into the function. The y-intercept is located at the point (0, c). The solutions of the quadratic equation ax 2 + bx + c = 0 correspond to the roots of the function f(x) = ax 2 + bx + c, since they are the values of x for which f(x) = 0. As shown in Figure 2, if a, b, and... Clearly, the discriminant of the given quadratic equation is zero and coefficient of x\(^{2}\) and x are rational. Therefore, the roots of the given quadratic equation are real, rational and equal. 4.

## How To Find The Value Of The Discriminant

Solving questions involving nature of roots and discriminant There are four different types of questions shown in this video and how to solve them. First type : Find the range of values of p for which the equation 4x^2 +12x +15 = p(4x + 7) has two real distinct roots.

- (5) If the roots of the equation 2x² + 8x - m³ = 0 are equal , then find the value of "m" Question 1 : Examine the nature of the roots of the following quadratic equation.
- As we see in Figure 3 (cell R22), the p-value for Box’s test is 3.4E-06, which indicates heterogeneity of covariance matrices, and so we will use quadratic discriminant analysis. We therefore need to calculate the individual covariance matrices as shown in Figure 2 (only two of the five covariance matrices and their inverses are shown in the figure).
- If you've used the Quadratic Formula before, finding the discriminant should feel like a shortcut. You don't need to use the whole formula, you just find the value of b squared minus 4ac. To do this, first make sure the equation is set equal to 0 and identify a, b, and c. a is the coefficient of the x-squared term, b is the coefficient of the x term and c is the constant. Plug the values into
