Dear (người nhận),
I hope this letter finds you in good health and high spirits. I wanted to take this opportunity to tell you about the family rules that we have in my home. Family rules are important as they help create a harmonious and respectful environment for everyone.
Firstly, we believe in open communication. We encourage everyone in the family to express their thoughts and feelings freely, while also listening to others with respect and empathy. This helps us understand each other better and resolve conflicts peacefully.
Secondly, we have a rule of mutual respect. We treat each other with kindness and consideration, regardless of age or relationship. We believe that everyone's opinions and choices should be valued, and we strive to support and encourage each other in our endeavors.
Furthermore, we have a rule of shared responsibilities. We believe that everyone in the family should contribute to the household chores and responsibilities. This fosters a sense of teamwork and teaches us the importance of taking care of our living space.
Lastly, we have a rule of quality time. We prioritize spending time together as a family, whether it's through shared meals, outings, or game nights. This helps us strengthen our bond and create lasting memories.
These family rules have helped us maintain a loving and respectful environment at home. I would love to hear about your family rules and how they contribute to your household dynamics.
Take care and write back soon!
Warm regards,

A=x2+10x+35=x2+10x+25+10=x2+2*x*5+52+10=(x+5)2+10
Ta có: (x+5)2>=0(với mọi x)
=> (x+5)2+10>=10(với mọi x)
hay A>=10(với mọi x)
Do đó, GTNN của A là 10 khi: (x+5)2=0
x+5=0
x=0-5
x=-5
Vậy GTNN của A là 10 tại x=-5
