Question

1 Solve: X X-1 +- = 2 x-1 X 2 2​

Answer 1

Answer:

(x−2)

1

+

(x−1)

2

=

x

6

=

(x−2)(x−1)

x−1+2x−4

=

x

6

=x(3x−5)=6(x−2)(x−1)

=3x

2

−5x=6(x

2

−x−2x+2)

=3x

2

−5x=6x

2

−18x+12

=13x−3x

2

−12=0

=3x

2

−13x+12=0

=3x

2

−4x−9x+12=0

=x(3x−4)−3(3x−4)=0

(3x−4)(x−3)

so, x=3 or x=

3

4
