ответ: решение на фото.
Объяснение:
t₁= - 5/12, t₂=1
Объяснение:
(2t+1)/(2t+0,5)=6t/5
2t=1/2t+1/2=6*t/5
2t+1/2t+1/2=6t/5
2t+1/4t+1/2=6t/5
(2t+1)*2/4t+1=6t/5
4t+2/4t+1=6t/5
5(4t+2)=6t*(4t+1)
5(4t+2)-6t*(4t+1)=0
20t+10-6t*(4t+1)=0
20t+10-24²-6t=0
14t+10-24²=0
-24t²+14+10=0
12t²-7t-5=0
12t²+5t-12t-5=0
t*(12t+5)-12t-5=0
t*(12t+5)-(12t+5)
(12t+5)*(t-1)=0
12t+5=0
t-1=0
t= -5/12,t
- 0,25
t=1
t= -5/12,t - 1/4
