jawab cepat,jngn ngasal cepat yah
Penjelasan dengan langkah-langkah:
[tex]soal \: 1 \\ {x}^{2} + 14x + 45 = 0 \\ (x \times x) + 14x + 45 = 0 \\ x + 14x + 45 = 0 \\ 15x + 45 = 0 \\ 60x = 0 \\ x = \frac{0}{60} = 60 \\ soal \: 2 \\ {x}^{2} - 16x + 55 = 0 \\ (x \times x) - 16x + 55 = 0 \\ x - 16x + 55 = 0 \\ - 15x + 55 = 0 \\ 40x = 0 \\ x = \frac{0}{40} = 40 \\ soal \: 3 \\ {x}^{2} - 14x - 32 = 0 \\ (x \times x) - 14x - 32 = 0 \\ x - 14x - 32 = 0 \\ - 13x - 32 = 0 \\ - 42x = 0 \\ x = \frac{0}{ - 42} = - 42[/tex]
