These solutions may be both real, or both complex. Among his many other talents, Major General Stanley in Gilbert and Sullivan's operetta the Pirates of Penzance impresses the pirates with his knowledge of quadratic equations in "The Major General's Song" as follows: "I am the very model...
Solving equations is the central theme of algebra. All skills learned lead eventually to the ability to solve equations and simplify the solutions. In previous chapters we have solved equations of the first degree. You now have the necessary skills to solve equations of the second degree, which ...
Plotting on a graph is another method of solving quadratic equations. The solution of the equation is obtained by reading the x-intercepts of the graph. In a graph, if there is no x – intercepts, then an equation has no real solutions. Recommended Worksheets One-Variable Equations (Employmen...
Any equation which has only terms with x2, x and numbers can be turned into the form ax2 + bx + c = 0, and then solved using the formula.Because you can have b plus or minus the square root, quadratic equations always have two solutions, as shown in the info box above. They ...
Practice Questions on Quadratic Equations 1. Assume that y = f(x) is a quadratic function with the highest power on x being 2. Then, how many different cases exist for solutions of the equation f(x) = 0. Describe the graphical situation in each case. 2. A ball is shot out of a...
Quadratic Equations can be factored Quadratic Formula: x = −b ±√(b2 − 4ac) 2a When the Discriminant (b2−4ac) is: positive, there are 2 real solutions zero, there is one real solution negative, there are 2 complex solutionsMath...
Quadratic equations characterize a great number of phenomena in the real world, such as where a rocket ship will land, how much to charge for a product or how long it will take a person to row up and down a river. Because of their wide variety of applications, quadratics have profound ...

The quadratic formula is used to determine the real (or complex) solutions for any quadratic equation. It is generally used in instances where other methods of solving, such as factoring, are not easily done. How do you solve quadratic equations? To solve a quadratic equation, set the equatio...
Solving for x, we get two different values :x = 2andx = -3 So we have our solutions, but what does this mean? Observing the equations, we can see that they can be worked with as two seperate linear equations. Let’s set both ...
