Use the quadratic formula to solve quadratic equations with complex solutions Connect complex solutions with the graph of a quadratic equation that does not cross the xx-axisWe have seen two outcomes for soluti
It is a wonder why the equations are called "quadratic," when the root "quad" tends to mean "four" - shouldn't this apply to fourth-degree equations (incidentally, these are calledquartic)? The naming of second-degree equations, "quadratic," has to do with the roots of mathematics, whi...
How do you find quadratic equations if you are only given the solution? Find all real solution to the quadratic equation x^2 + 2 x = - 1. Find all real solution to the quadratic equation x^2 + 2 = x + 5 How to tell if a quadratic has no solution? ...

If step 5 is not possible, then the equation has no real solution. These steps will help in solving the equations in the following exercise. THE QUADRATIC FORMULA OBJECTIVES Upon completing this section you should be able to: Solve the general quadratic equation by completing the square. ...
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...
What are the three methods of solving quadratic equations? Explain. How do you know there is no real solution to the quadratic equation x^2 + x + 14 = 0? How could you know if a quadratic equation will have one, two, or no solutions? How do you know if a quadratic equation will ...
No real solution (happens when they never intersect) One real solution (when the straight line just touches the quadratic) Two real solutions (like the example above)Time for another example!Example: Solve these two equations: y - x2 = 7 - 5x 4y - 8x = -21 Make both equations into "...
