^2 x + 3 log (^x2-3x+2)= 2 x + 3 log (5 x -8)
x² – 3x + 2 = 5x – 8
x² – 8x + 10 = 0
x1,2 = (-b ± √(b² – 4ac))/2a
= (8 ± √(8² – 4(1)(10)))/2
= (8 ± 2√6)/2
= 4 ± √6
Syarat:
• 2x + 3 > 0
2x > -3
x > -3/2
x > -1,5
• 2x + 3 ≠ 1
2x ≠ -2
x ≠ -1
• x² – 3x + 2 > 0
(x – 2)(x – 1) > 0
x < 1 atau x > 2
• 5x – 8 > 0
5x > 8
x > 8/5
x > 1,6
Maka: HP = {x = 4 + √6}
