Use the discriminant to describe the roots of each equation. then select the best description. x2 - 5x - 4 = 0 double root real and rational roots real and irrational roots non-real roots

Third option: Real and Irrational roots.

Step-by-step explanation:

For a Quadratic equation:

The Discriminant can be found with this formula:

Given the following Quadratic equation:

You can identify that:

Then, substituting these values into the formula for find the Discriminant, you get that this is:

Therefore, since the Discriminant is positive () but it is not a perfect square, then the roots of the equation are Real and Irrational.

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
