Question

6(r/r-1)^2 - 7(r/r-1) - 5 = 0. Find all real solutions ( let w = r/r-1)

Answer 1

Is r= -5/3 and r = 1/3 correct?

Answer 2

w = -1/2 , w = 5/3

sub back in to solve for r..

r/r-1 = -1/2
r = -1/2(r-1)
r = -1/2r + 1/2
3/2 r = 1/2
r = 1/12

r/r-1 = 5/3
r = 5/3(r-1)
r = 5/3 r - 5/3
-2/3 r = - 5/3
r = 5/2
