2X² + 2 = X² + 3X
2X² - X² - 3X + 2 = 0
X² - 3X + 2 = 0
Kalau ditanya nilai X
X² - 3X + 2 = 0
X² - 2X - X + 2 = 0
X(X - 2) -1 (X -2) = 0
(X - 1)(X - 2) = 0
X - 1 = 0 atau X - 2 = 0
X = 1 atau X = 2
2x²+2 =x²+3x
2x²-x²-3x+2
x²-3x+2=0
Jadi bentuk umum persamaan kuadratnya adalah x²-3x+2=0
Insyaallah bermanfaat
