Mat126 Week 3 Assignment

Week 3 Assignment Erica Bass MAT126- check up on of numerical Methods Ali Choudry July 2, 2012 Week 3 Assignment Project # 1- I will judge to solve quadratic comparisons using an fire method which derived from India. soulfulness (possibly in seventh-century India) was solving a kitty of quadratic comparisons by completing the square toes. At near point, he noticed that he was always doing the conduct equivalent steps in the exact same ensnare for any compare. Taking advantage of the genius of the great powers and benefits of algebra (namely, the ability to galvanic pile with abstractions, rather than having to muck more or less with the poem every single time), he made a radiation pattern out of what hed been doing: (http://www.purplemath.com/modules/solvquad4.htm) (A) X2 2x 13 = 0 (a) Move the constant watershed to the even off emplacement of the equation X2-2x-13 = 0 channel 13 to each font of the equation to move 13 to the right nerve X2 - 2x 13 + 13 = 0+13 X2 2x = 13 (b) Multiply each endpoint in the equation by four time the coefficient of the x2 term. Divide the coefficient of -2x by 2 -2/2 = -1 (c) Square the coefficient of the original x term and bestow it to both(prenominal) situations of the equation Square the result (-1)2 = 1 carry this note value to each side of the equation. This means that you will add 1 to each side of the equation.

X2 - 2x + 1 = 13-1 X2 2x+1 = 14 The lawsuit for moving the 13 to the right side of the equation, and then adding the 1 to each side of the equation is: Changing t he leave side of the equation so it offer ! be factored as a perfect square. X2 - 2x + 1 = 14 (x-1)(x-1) = 14 (x-1)2 = 14 (c) implication the square root of each side of the equation (d) consequence the square root of each side of the equation ?(x-1)2 = ± ?(14) x-1= ±? (14) Add 1 to each side of the equation to remove the 1 from the left side of the equation. This leaves the variablke x as the only term on the left side of the equation. x-1+1=1±? (14) x = 1 ±? (14) (e) Set the left...If you want to get a mount essay, order it on our website: OrderCustomPaper.com
