Albatta, bu erda pre-kalkulus o'rganishni istagan kishi uchun echish uchun boshlang'ich muammo: * ** kvadrat tenglamaning ildizlarini hal qiling: ** `` x^2 - 2x + 1 = 0 `` Ushbu tenglamani kvadrat formulasi yordamida hal qilish mumkin: `` x = (-b ± √(b^2 - 4ac)) / 2a `` ` Ushbu holda, a = 1, b = -2, va c = 1. kvadrat formulasi bu qiymatlar o'rnini, biz olish: `` x = (2 ± √(-2^2 - 4 * 1 * 1) / 2 * 1 `` ` Radikal ostida ifodani soddalashtirish, biz olish: `` x = (2 ± √4 - 4) / 2 ` ` ` kvadrat ildiz 4 - 4 - shunday biz: `` x =
