Question

(2х-1)(х+3)-х(х-2)АААААААААААААА ​

Answer 1

Ответ:

x²+7x-3

Объяснение:

Answer 2

To simplify the expression (2x-1)(x+3)-x(x-2), you can use the distributive property (also known as the FOIL method) to multiply the terms within each set of parentheses and then simplify the expression:

(2x-1)(x+3) - x(x-2)

First, multiply the terms within each set of parentheses:

(2x * x) + (2x * 3) + (-1 * x) + (-1 * 3) - (x * x) + (x * 2)

Now, simplify the expression further by combining like terms:

2x^2 + 6x - x - 3 - x^2 + 2x

Combine the x^2 terms:

(2x^2 - x^2) + 6x - x + 2x - 3

Now, subtract the x^2 terms:

x^2 + 7x - x + 2x - 3

Combine like terms again:

x^2 + 8x - 3

So, the simplified expression is:

x^2 + 8x - 3
