Nyatakan persamaan 2(x² + 1) = x(x + 3) dalam bentuk umum persamaan kuadrat.
A. 2(x² + 1) = x(x + 1) ⇔ 2x² + 2 = x² + 3x ⇔ x² – 3x + 2 = 0
B. 2(x² + 1) = x(x + 3) ⇔ 2x² + 2 = x² + 3x ⇔ x² – 3x + 2 = 0
C. 2(x² + 1) = x(3 + x) ⇔ 3x² + 2 = x² + 3x ⇔ x² – 3x + 2 = 0
D. 2(x² + 1) = x(3 + x) ⇔ 2x² + 3 = x² + 3x ⇔ x² – 3x + 2 = 0
