Solve x² + x - 6 = 0 — x = -3 or x = 2

Problem

$x^2 + x - 6 = 0$

Step-by-step solution

Carilah dua bilangan yang hasil kalinya $-6$ dan jumlahnya $1$ .
Pasangan $(3, -2)$ : $3 \cdot (-2) = -6$ ✓, $3 + (-2) = 1$ ✓.
Faktorkan: $(x + 3)(x - 2) = 0$ .
Setarakan setiap faktor dengan nol: $x = -3$ atau $x = 2$ .

Answer

$x = -3 \quad \text{or} \quad x = 2$
