|2X+1|=|3X-2| bntu jwab

Penjelasan dengan langkah-langkah:

|2x + 1| = |3x – 2|

Ingat !

|x| = √x²

maka :

√(2x + 1)² = √(3x – 2)²

(2x + 1)² = (3x – 2)²

(2x + 1)² – (3x – 2)² = 0

Ingat !

a² – b² = (a + b)(a – b)

maka :

[(2x + 1) + (3x – 2)][(2x + 1) – (3x – 2)] = 0

(5x – 1)(-x + 3) = 0

x = 1/5 atau x = 3

Jadi, HP = {1/5, 3}

 

Semoga Bermanfaat
