What is in extraneous solution to the equation b/b-7 - 2/b = 7/ b-7 ?
alexandr402 [8]

Answer:

b = 2 or b = 7

Step-by-step explanation:

b/(b-7) - 2/b = 7/ (b-7)

b * b - 2(b - 7) = 7 * b

b^2 - 2b + 14 = 7b

b^2 - 9b + 14 = 0

(b - 2)(b - 7) = 0

b - 2 = 0; b = 2

b - 7 = 0; b = 7

Answer

b = 2 or b = 7
