Polynomial with complex root
nth degree polynomial with real coefficients has precisely n complex roots . Hence when all root cannot be real. Complex root with Polynomial
Arithmetics of complex no
imaginary number is any number of the form a + bi where a and b are real numbers. Addition and Subtraction of complex numbers is to add or subtract real parts and the imaginary parts. complex no
Polynomial
The polynomials are an expression involving a sum of powers in one or more variables multiplied by coefficients and constant. Polynomial linear , quadratic etc as per value of n=1, n = 2 etc . We can graph the polynomial for finding solution. Another polynomial is also use for curve as well as st. line. As […]
Co-ordinate geometry-1
Coordinate also called ordered pair. Hence manipulation of coordinate such as Determine the distance between these points. Find the equation, midpoint, and slope of the line segment. Determine if the given lines are perpendicular or parallel. Also deal with graphic representation. Coordinate geometry
Completing Square
Completing the Square is to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial. Completing the square is a technique for converting a quadratic polynomial of the form ax2 + bx + c to a(x-b)2+c. Hence this method is used to convert. Similarly […]
