WebTo see this, we set b 2 −4ac = 0 in the quadratic formula to get, Notice that is the x-coordinate of the vertex of a parabola. Thus, a parabola has exactly one real root when the vertex of the parabola lies right on the x-axis. The simplest example of a quadratic function that has only one real root is, y = x 2, where the real root is x = 0. WebQuestion: *4.1 (Algebra: solve quadratic equations) The two roots of a quadratic equation, for example, ax2 + bx + c = 0, can be obtained using the following formula: h2 - 4ac 2a and r2 2a b2 - 4ac is called the … convert tl to ruble WebThe solution to the quadratic equation is given by the quadratic formula: The expression inside the square root is called discriminant and is denoted by Δ: This expression is … WebApr 10, 2024 · A quadratic equation in form ax2 + bx + c = 0 cannot have one imaginary solution.. What is a quadratic equation? The quadratic formula helps to evaluate the … crypto poocoin WebAug 11, 2012 · Instead you have only and exact 3 situations here: when D > 0 - you have 2 different real roots, when D = 0 - you have exactly one real root (or 2 similar roots), and when D < 0 - you do not have any real roots. Thats all and you do not have a need for checking any coefficients, but only discriminant. – 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 … convert tl to pounds WebWe have also learned that it is possible to take the square root of a negative number by using imaginary numbers.
