Cevap:
1)
[tex] {x}^{2} + x - 2 = 0 \\ (x + 2).(x - 1) = 0 \\ \\ x + 2 = 0 \\ x = - 2 \\ \\ x - 1 = 0 \\ x = 1[/tex]
2)
[tex] {x}^{2} + 7x + 12 = 0 \\ (x + 4).(x + 3) = 0 \\ \\ x + 4 = 0 \\ x = - 4 \\ \\ x + 3 = 0 \\ x = - 3[/tex]
3)
[tex] {x}^{2} - 7x + 6 = 0 \\ (x - 6).(x - 1) = 0 \\ \\ x - 6 = 0 \\ x = 6 \\ \\ x - 1 = 0 \\ x = 1[/tex]
4)
[tex] {x}^{2} + 3x - 10 = 0 \\ (x + 5).(x - 2) = 0 \\ \\ x + 5 = 0 \\ x = - 5 \\ \\ x - 2 = 0 \\ x = 2[/tex]
