WebIn other words there is no real solution for those values of k. For k=-6 & k=2, which you found the function (with x) has only one x-intercept (which is the vertex). For k<-6 & k>2, the function has two solutions (x-intercepts). So, you find the discriminant in order to figure out for … WebFor a system of two linear equations and two variables, there can be no solution, exactly …

can quadratic equations have two imaginary solutions? Explain
WebMar 30, 2024 · The term real root means that this solution is a number that can be whole, positive, negative, rational, or irrational. While numbers like pi and the square root of two are irrational numbers, rational numbers are zero, whole numbers, fractions and decimals. However, the solution to an equation can be real roots, complex roots or imaginary roots. The Standard Formof a Quadratic Equation looks like this: 1. a, b and c are known values. acan't be 0. 1. "x" is the variableor unknown (we don't know it yet). Here are some examples: See more Play with the "Quadratic Equation Explorer" so you can see: 1. the function's graph, and 2. the solutions (called "roots"). See more As we saw before, the Standard Formof a Quadratic Equation is But sometimes a quadratic equation does not look like that! For example: See more There are usually 2 solutions (as shown in this graph). And there are a few different ways to find the solutions: See more WebExample. Our goal is to find the number of solutions to this quadratic equation: 9 x 2 + 42 … kuzman lumber
