In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is where x represents a variable, and a, b, and c, constants, with a ≠ 0. (If a = 0, the equation becomes a linear equation.) The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term. The term "quadratic" comes from quadratus, which is the Latin word for "square." Quadratic equations can be solved by factoring, completing the square, graphing, Newton's method, and using the quadratic formula (given below). One common use of quadratic equations is computing trajectories in projectile motion. Plots of real-valued quadratic function ax + bx + c, varying each coefficient separatelyFrom Wikipedia under the

From Google News Search: "Quadratic equations" Algebra help.. What type of solution do you get for quadratic equations where D<0? ? Q. The question is what type of solution do you get for quadratic equations where D<0? Give reason for you answer and provide an example. Imaginary Solutions is what you get for quadratic equation where D<0, right? What would be an example? Asked by Paula - Sat Oct 25 17:10:54 2008 - - 2 Answers - 0 Comments A. Actually the solution is not necessarily imaginary,it is complex. There is a fine line of difference between imaginary and complex numbers. Complex nos= real nos. + imaginary nos. Proper example would be : Solve : 2x^2+2x+1=0 By reducing it to formula we get: x=(-2 +,- sqrt(-4))/2; solving we would get: Either x=(-1+i)/2 or (-i-1)/2. Answered by SoumyoM - Wed Oct 29 14:34:32 2008 Im having some trouble with quadratic equations so could someone help me with this question? Q. Explain how to to check the solutions of a quadratic equation of the form x2+bx+c. Then use the result to check that 3+2i and -3+2i are solutions of the equation x2+6x+13=0? How would I find if those are solutions? Asked by kimberly b - Mon Jul 6 22:31:11 2009 - - 3 Answers - 0 Comments what is a practical use for quadratic equations in technology?
Q. i know this sounds really stupid, but we have to do an assignment for class in which we must find examples as to how quadratic equations are used in technology. PLEASE help!!! :D thank youuu Asked by Megan Y - Fri May 22 01:22:41 2009 - - 1 Answers - 0 Comments From Yahoo Answer Search: "Quadratic equations" |
