Question

(3x + 1)(5 - 2x) + 6x² = 5​

Answer 1

Ответ:

Пошаговое объяснение:

(3x + 1)(5 - 2x) + 6x² = 5​

15x-6x²+5-2x+6x²=5

13x=0

x=0

Answer 2

To solve the equation, let's first simplify the expression on the left-hand side by expanding the brackets:

(3x + 1)(5 - 2x) + 6x² = 5

Using the distributive property, we multiply each term in the first bracket by each term in the second bracket:

(3x * 5) + (3x * -2x) + (1 * 5) + (1 * -2x) + 6x² = 5

Simplifying further:

15x - 6x² + 5 - 2x + 6x² = 5

Combining like terms:

(15x - 2x) - 6x² + 5 + 6x² = 5

13x - 6x² + 5 + 6x² = 5

Rearranging the terms:

13x - 6x² + 6x² + 5 = 5

The terms with x² cancel out:

13x + 5 = 5

Subtracting 5 from both sides:

13x = 0

Dividing both sides by 13:

x = 0

Therefore, the solution to the equation (3x + 1)(5 - 2x) + 6x² = 5 is x = 0.
