WebWhen the plane does intersect the vertex of the cone, the resulting conic is called a degenerate conic. Degenerate conics include a point, a line, and two intersecting lines. The equation of every conic can be written in the following form: ... If B 2-4AC < 0, the conic is a circle, or an ellipse. If B 2 - 4AC = 0, the conic is a parabola. WebMay 16, 2024 · It is called the Discriminant, because it can "discriminate" between the possible types of answer: when b2 − 4ac is positive, we get two Real solutions. please mark as brainlist.

Webb^2 - 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero the equation has one root. daily horoscope by astrostyle WebThe answers that you found (for k) are when the discriminant equal 0 (b^2-4ac=0) -- which means that the function has only one solution. When you graph (k+4)^2-4(k+7), you get a convex parabola with vertex (-2,-16) and x-intercepts at (-6,0) and (2,0). That implies that … WebThe quantity b 2 - 4ac is called the _____ of a quadratic equation. If it is _____ , the equation has no real solution. Formula Formula A polynomial with degree 2 is called a … coc 9 max base photo WebThe expression `b^2 − 4ac` is called the discriminant and in some books you will see it written with a Greek upper case Delta, like this `Delta = b^2 − 4ac`. Example 1. Solve `2x^2- 7x - 5 = 0` using the quadratic formula. Answer. By inspection, we can see that: `a = 2`, `b = -7` and `c = -5`.
