Please show some work if you not it’s okay :)

If the discriminant if a quadratic equation is 4 which statement describes the roots?

In the picture below, line pq is parallel to line rs, and the lines are cut by a transversal, line tu. the transversal is not perpendicular to the parallel lines. note: figure is not drawn to scale. which of the following are congruent angles?

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
