Question

2(х – 1) – 5х(3х – 1)

Answer 1

Ответ:

7х - 2 - 15$x^{2}$

Объяснение:

2(х-1) - 5х(3х-1) = 2x - 2 -15$x^{2}$ + 5x = 7x - 2 - 15$x^{2}$

Answer 2

Ответ:

2(х – 1) – 5х(3х – 1) = 2х - 2 - 15х^2 + 5х = 7х - 15х^2 - 2

Answer 3

To simplify the expression 2(х - 1) - 5х(3х - 1), you can follow these steps:

1. Distribute the 2 on the first term and the -5x on the second term:

   2(х) - 2(1) - 5x(3х) + 5x(1)

2. Now, simplify each term:

   2x - 2 - 15x^2 + 5x

3. Combine like terms:

   (2x + 5x) - 2 - 15x^2

4. Add the coefficients of like terms:

   7x - 2 - 15x^2

So, the simplified expression is:

7x - 2 - 15x^2
