Відповідь:

Якщо один з коренів рівняння x2+2bx-3=0 дорівнює 3, то другий корінь можна знайти за формулою відношення коренів: x1 * x2 = c/a = -3/1 = -3. Отже другий корінь дорівнює -3/3 = -1.

Тепер ми можемо знайти коефіцієнт b. Знаючи суму коренів (x1 + x2 = -b/a), ми можемо обчислити b: 3 + (-1) = 2 = -b => b = -1.

Покрокове пояснення:


kent228one: якщо можеж зроби відповідь найкращою яж старався ;)
