The discriminant of the quadratic formula is the quantity under the radical, latex {{b}^{2}}4ac/latex It determines the number and the type of solutions that a quadratic equation has If the discriminant is positive, there are latex2/latex real solutions If it is latex0/latex, there is latex1/latex real repeated solution2/28/14 · y = x^2 4x 32 = x^24x4 28 = (x2)^2 28 So the vertex is at (2,28) the axis is x=2 Naturally, the minimum is at the vertex 28 Check the factors of 32 We want two of them which differ by 4 (x8)(x4) Not sure how the discriminant relates to #47/1/ · To find the zeros of the quadratic function y = x^{2} 2 on the graph first we have to plot the quadratic function y = x^{2} 2 on the graph From the graph, we can see that the quadratic function y = x^{2} 2 cuts the xaxis at x = 14 and x = 14 So the quadratic function y = x^{2} 2 has two real zeros and they are x = 14 and x = 14

The Discriminant tells about the nature of the roots of quadratic equation In quadratic equation formula, we have \( b^2 4ac \) under root, this is discriminant of quadratic equations There are three cases for discriminant if \( b^2 4ac = 0 \), thenPutting y = x^2 4x 4 into a perfect square form then we halve the 4 to make 2 then square the 2 to make 4 So luckily for us we don't have to add and take away anything, since it's already a perfect square Now, since it's a perfect square already we can factorise y = x^2 4x 4 as follows y = (x 2The figure below shows the graph of the quadratic function written in general form as latexy={x}^{2}4x3/latex In this form, latexa=1,\text{ }b=4/latex, and latexc=3/latex When we consider the discriminant, or the expression under the radical, latex{b}^{2}4ac/latex, it tells us whether the solutions are real numbers or
