What is 2a3-5a2-39 In Rationalizing quadratics?
In rationalising quadratics 2a3 - 5a2 - 39 is an irrelevance. It is not a quadratic but a cubic and so not within the defined scope.
A quadratic equation has how many real roots?
Quadratics can two, one or no real roots.
Can all quadratics be solved by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
What is the quadratic formula for?
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
How do you do these quadratics word problems?
In order to know how to do certain quadratic word problem one needs to know what the problem is.

What are the pros and cons of solving quadratics by using the quadratic formula?
One pro of using the quadratic formula is that it will produce complex (imaginary) roots just as easily as it can produce real roots. (Factoring with imaginary numbers is a kind of a nightmare!) Another pro to the quadratic formula is that it eliminates the frustrating guess-and-check process. A con of the quadratic formula is that, when it comes to more simple problems, it is usually more time-consuming. A lot of textbook problems are quite easy to factor in your head--it is often not worth the effort of plugging numbers into a long formula. A second con of the quadratic formula is that it is quite long--you might write out the formula, accidentally forget a letter, and whole thing is useless. It's much easier to see that your work is correct when you're factoring.
What is the difference between quadratic formula and quadratic equation?
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.
What is the application of quadratic equation to the lab technicians?
None, quadratics are a torture method invented by a particularly cruel middle age teacher.
