Question

1) x2 + 4x - 10=0
2) 5x2 - 10x - 24=0
3) 12x2 +10x + 3=0
4) x2 +10x -7200 =0

пожалуйста с решением

Answer 1

2. $2x + 4x - 10 = 0 \\ 6x = 10 \\ x = \frac{5}{3}$
3. $10x - 10x - 24 = 0 \\ - 24 = 0 \\ \\ x = 0$
4. $2x + 10x + 3 = 0 \\ 34x + 3 = 0 \\ 34x = - 3 \\ x = - \frac{3}{34}$
5. $2x + 10x - 7200 = 0 \\ 12x - 7200 = 0 \\ x = 600$
