PROBLEM 2. Find the (unique) quadratic polynomial such that all three of the following are true: . All the coefficients are integers. • The coefficient of x² is 4. 7+ √6 is one of the roots. • Student Solution 1: (x+ (7+√6))(x-(7-√6)) x² + (7²) (7=√6)x= (7+√6) (7-√6) (7 + 86-7-86) X 49+7√5-76456 (43) 4x² - 43 I know •Know that this does not satisfy all the Conditions. We must use some formula/ technique that includes that a = 4 and that the root = 7+√6.
Student Solution 2: X-(7+√6)=0 X =(7+√6) 4x² + bx + c = 0 4 (7+√√5)² + b(7+√√6) +C =0 4(49+ 6) + b(7+√√) +C =0 +b(7+√√6) +C =0 196 + 24 220 +b(7+√√6) + C = 0 6 (7+√6) + C = - 220 7b+ √6²b +C = -220 4 -6=7 6x -7 Student Solution 3: "4x² +bx+c 4x² - 7x + ( 20 I dari know 6²-4ac = 96 6²-161 =96 49-166=96 161 = 45 (=-45 16 ==
