Astudent solves the following equation for all possible values of x: 8/x+2 = 2/x-4 his solution is as follows: step 1: 8(x – 4) = 2(x + 2) step 2: 4(x – 4) = (x + 2) step 3: 4x – 16 = x + 2 step 4: 3x = 18 step 5: x = 6 he determines that 6 is an extraneous solution because the difference of the numerators is 6, so the 6s cancel to 0. which best describes the reasonableness of the student’s solution? a) his solution for x is correct and his explanation of the extraneous solution is reasonable. b)his solution for x is correct, but in order for 6 to be an extraneous solution, both denominators have to result in 0 when 6 is substituted for x. c)his solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x. b)his solution for x is incorrect. when solved correctly, there are no extraneous solutions.
