LCD is a special case of LCM .
to find LCD find LCM of denominators in fraction.
here given expression is
here denominator are (x-2) and (x+1)
To find LCD find Lcm of (x-2) and (x+1)
We have no common multiple for x-2 and x+1 .so to get Lcm multiply both.
so LCM LCD is (x-2)(x+1)
now multiply LCD on both side
now cancel common terms in numerator and denominator of different parts of equation
take (x+1) as common in left side
now open brackets
2x+ 2 = 3x-6
3x-2x= 2+6
x= 8
so solution is x=8
3 - 1 = - 2
3 -(x 2)(x1) x2)(1) 1 2
( 2) (x1) 1 2) (x) -1 (r -2) (x1) 2
(x 1)- (-2) ( 1)3(TI2)
1)(- 2) 3(x - 2)
21 2(r1)3(r
