x^2 -5x + 6 = 2x + 24
x^2 - 7x - 18 = 0
(x-9)(x+2) = 0
x = 9 atau x = -2
HP {9}
x - 2 > = 0_ x > = 2
2x + 24 > = 0_ x > = -12
log ( x - 3) + log (x -2) = log (2x+24)
=> log (x-3)(x-2) = loh (2x+24)
=> x^2 -5x +6 = 2x +24
=> x^2 -7x - 18 =0
=> (x +2)(x-9)=0
=> x = -2 atau x = 9
,HP = { 9 } untuk x = -2 tidak memenuhi syarat numerus (1) dan (2)
