Final Paper for Survey of Mathamatical Problems

Week 3 Written Assignment Carla Zemeckis Survey of numerical Methods instructor: Kevin Kuznia February 6, 2012 Project 1 In India they use a method for result quadratic comparisons. There are sextet stairs to firmness of purpose the compare. I will rise four different comparabilitys and the steps I use to scoop them. A) x²-2x-13=0 step virtuoso move the uninterrupted bourn to the right spatial relation of the equating. x²-2x-13=0 turns into x²-2x=13 to do this give 13 to couple military positions of the equation. standard two Multiply each limit in the equation by four times the coefficient of the x² term. x²-2x=13 turns into 4x²-8x=52 to do this multiply x² by 4. Gives you 4x² then 4*2x=8x and 13*4=52. ill-use triad four self-coloured the coefficient of the original x term and attach it to some(prenominal) side of the equation. 4x²-8x=52 turns into 4x²-8x+4=56 to do this 2²=4 add four to some(prenominal) sides. shad e four take the unbent result of both sides. 4x²-8x+4=56 turns into 2x-2=±7.48 to do this the lusty root of 4x² -8x +4 = 2x -2 and the square root of 56 is 7.48. shout five company the left-hand(a) field side of the equation equal to the positive square root of the do on the right side of the equation and solve for x. 2x-2= 7.48 and x= 4.74 to do this add 2 to both side of the equation 2x=9.48 then divide 2 by both sides and it gives you x= 4.

74 Step six set the left side of the equation equal to the negative square root of the number on the right side of the equation and solve for x. 2x-2= -7.48 and x = -2.74 to do this add 2 to both side of the equation 2x= -5.48 then div ide 2 by both sides of the equation to give ! you x= -2.74 Follow these steps for the rest of the equations. B) 4x²-4x+3=0 Step one 4x²-4x= -3 Step two (4x²-4x= -3)16 turns into 64x²-64x= -48 Step three 64x²-64x+16= -48+16 turns into 64x²-64x+16=-32 Step four 64x²-64x+16= -32 this is where the problem ends this method dot not work because you cannot vex the square root of -32. C) x²+12x-64=0 Step one x²+12x-64=0 turns into x² +12x=64 Step two x²...If you call for to push a full essay, order it on our website: OrderEssay.net
