Question

5x³-x(2x-3)=3x Срочно помогите​

Answer 1

Ответ:

$5x^3-x(2x-3)=3x\\5x^3 - 2x^2 + 3x = 3x\\\\5x^3 - 2x^2 = 0\\x^2(5x - 2) = 0\\x1 = 0\\x2 = \frac{2}{5}$

Answer 2

5x³ - x(2x - 3) = 3x,

5x³ - 2x² + 3x - 3x = 0,

5x³ - 2x² = 0,

x²(5x - 2) = 0.

Отсюда получаем 2 решения:

x² = 0, х = 0.

5x - 2 = 0. х = 2/5.
