Answer 1

Answer:

try to read question carefully you will get your answer in it only takes

Answer 2

Answer:

$x2 = 3x -1, x2 - 3x + 1 = 0, a=1, b=-3, c=1. 2(x2 - 2x) = 5, 2x2 - 4x - 5 = 0 , a=2, b=-4, c=-5. x(x-1) = 3, x2 - x - 3 = 0, a=1, b=-1, c=-3. 5 + 1/x - 1/x2 = 0, 5x2 + x - 1 = 0, a=5, b=1$
