Tentukan himpunan penyelesaian dari persamaan 2x²-x-3=0!

// Bentuk ax^2 + bx + c = 0
a.c = m × n
b = m + n
ax^2 + mx + nx + c = 0

2x^2 - x - 3 = 0; a = 2, b = -1, c = -3

2.(-3) = -6 = -3 × 2
- 1 = -3 + 2

2x^2 - 3x + 2x - 3 = 0
x(2x - 3) + 1 (2x - 3) = 0
(x + 1).(2x - 3) = 0

x1 + 1 = 0
x1 = -1

2x2 - 3 = 0
2x2 = 3
x2 = 3/2

Semoga bisa bantu ya
