2.6-bo'lim: Kvadrat tenglamalar - II qism

1-3 muammolar uchun kvadratni to'ldiring.

1. \({x^2} + 8x\) Yechim
2. \({u^2} - 11u\) Yechim
3. \(2{z^2} - 12z\) Yechim

4 - 8 masalalar uchun kvadrat tenglamani kvadratni to'ldirish orqali yeching.

1. \({t^2} - 10t + 34 = 0\) Yechim
2. \({v^2} + 8v - 9 = 0\) Yechim
3. \({x^2} + 9x + 16 = 0\) Yechim
4. \(4{u^2} - 8u + 5 = 0\) Yechim
5. \(2{x^2} + 5x + 3 = 0\) Yechim

9-13-masalalar uchun kvadrat tenglamani yechish uchun kvadrat formuladan foydalaning.

1. \({x^2} - 6x + 4 = 0\) Yechim
2. \(9{w^2} - 6w = 101\) Yechim
3. \(8{u^2} + 5u + 70 = 5 - 7u\) Yechim
4. \(169 - 20t + 4{t^2} = 0\) Yechim
5. \(2{z^2} + z - 72 = {z^2} - 2z + 58\) Yechim
