Question

X (5x-x+2) - (5х – 2 + 4х) - х(х - х - 3)​

Answer 1

Ответ:

$4x^{2} -4x + 2$

Объяснение:

$x(5x-x+2)-(5x-2+4x)-x(x-x-3)$

$x(4x+2)-(9x-2)-x(-3)$

$4x^{2} + 2x - 9x + 2 + 3x$

$4x^{2} -4x + 2$

Answer 2

To simplify the given expression, you can follow these steps:

1. Distribute the coefficients within the parentheses:

   X(5x - x + 2) - (5x - 2 + 4x) - x(x - x - 3)

   This simplifies to:

   5x^2 - x^2 + 2X - (5x - 2 + 4x) - x(x - x - 3)

2. Continue simplifying within each set of parentheses:

   4x^2 + 2X - (5x - 2 + 4x) - x(x - x - 3)

3. Distribute the negative sign inside the second set of parentheses:

   4x^2 + 2X - 5x + 2 - 4x - x(x - x - 3)

4. Simplify the terms within the last set of parentheses:

   4x^2 + 2X - 5x + 2 - 4x - x(0 - 3)

   Since (x - x) equals 0, you can simplify further:

   4x^2 + 2X - 5x + 2 - 4x + 3x

5. Combine like terms:

   4x^2 + 2X - 5x + 2 - 4x + 3x = 4x^2 - 4x^2 - 5x - 4x + 3x + 2 + 2

   Now, simplify the terms:

   0 - 6x + 2 + 2

   -6x + 4

So, the simplified expression is -6x + 4.
