You must show all your working. (click for each stage of the answer) The equation x3 +10x=51 has a solution between 2 and 3. Use a trial and improvement method to find this solution. Give your answer correct to 1 decimal place. You must show all your working. (click for each stage of the answer) First we test a value which is half way between 2 and 3, x=2.5 is too small Then we test a value which is between 2.5 and 3, say x=2.7 is too small We then try another value between 2.7 and 3, say x=2.8 is too small is too big We test x=2.9 To decide if we should take 2.8 or 2.9 we test the value in the middle is too big Because the answer is too big we will choose the smaller value namely x=2.8 as our solution to one decimal place. You must show all this working out to gain full points for this question in the exam The equation x3 – 4x=24 has a solution between 3 and 4. Use a trial and improvement method to find this solution. Give your answer correct to 1 decimal place. You must Show all your working. Try x=3.5 too big Try x=3.2 too small Try x=3.3 too small Try x=3.4 too big To decide if we should take 2.8 or 2.9 we test the value in the middle Try x=3.35 too big Because the answer is too big we will choose the smaller value namely x=3.3 as our solution to one decimal place.
