📚QUADRATIC EQUATIONS haqida to‘liq tushuncha‼️ Kvadrat tenglama (quadratic equation) — bu ikkinchi darajali tenglama bo‘lib, umumiy ko‘rinishi: ax² + bx + c = 0 bu yerda a, b, c — sonlar (coefficients), va a ≠ 0. 🛠 Kvadrat tenglamani yechish usullari 1️⃣. Factoring (faktorlash): Tenglamani ko‘paytmalar ko‘rinishiga ajratib, ildizlarni (roots) topish mumkin. Masalan, x² - 5x + 6 = 0 faktorlarga ajratilib: (x - 2)(x - 3) = 0 ildizlar: x = 2 yoki x = 3. 2️⃣. Quadratic Formula (kvadrat formula): Har qanday kvadrat tenglama uchun ishlaydi. Formulasi: x = [-b ± √(b² - 4ac)] / 2a Bu yerda Discriminant (diskriminant): b² - 4ac Diskriminant ildizlar sonini aniqlaydi: Discriminant > 0 → 2 haqiqiy ildiz (real roots) Discriminant = 0 → 1 takroriy ildiz (repeated root) Discriminant < 0 → haqiqiy ildizlar yo‘q (no real roots), ildizlar kompleks sonlar (complex roots). Completing the Square (to‘liq kvadrat shakliga keltirish): 3️⃣. Completing the Square (to‘liq kvadrat shakliga keltirish): Tenglamani shunday shaklga keltirib, ildizlarni topish. 🎯 SAT Math qismida quadratic equations qaysi holatlarda uchraydi? ⏩Graphs of parabolas (parabola grafigi): vertex (cho‘qqi), axis of symmetry (simmetriya o‘qi), x-intercepts (ildizlar) ⏩Sum and product of roots (ildizlar yig‘indisi va ko‘paytmasi) formulalari ⏩Using discriminant (diskriminant yordamida ildizlar sonini aniqlash) ⏩Word problems (matematik masalalar) — fizik, geometriya yoki kundalik hayotdan misollar. 📲Ro‘yxatdan o‘tish uchun quyidagi havoladan foydalaning: https://docs.google.com/forms/d/e/1FAIpQLSdWOlW6JNlUnvslEQLralhSfKzMFojeiI5uoy_2i6hLd_rkfw/viewform?usp=sharing&ouid=102332035584121163014 📚"SAT FOUNDATION" kitobimiz buyurtmasi uchun: @satislomxonadmin 📞 +998 95 828 0233 O'quvchilarimiz natijalari:https://t.me/satislomxonresults 🤖Bizning BOT: t.me/sat_practice_tests_free_bot 📱Telegram 📱Instagram📱Youtube
