Question

0,5x (4x2-1)(5x2+2) упростите пожалуйста

Answer 1

0,5х(4х*1)(5х*4)
10х*4
* значит умножить

Answer 2

0,5*(4*2-1)*(5*2+2). 0,5*84=42

Answer 3

To simplify the expression 0.5x + (4x^2 - 1)(5x^2 + 2), we can start by expanding the second term using the distributive property.

The expression becomes:

0.5x + (4x^2)(5x^2) + (4x^2)(2) - (1)(5x^2) - (1)(2)

Simplifying further:

0.5x + 20x^4 + 8x^2 - 5x^2 - 2

Combining like terms:

20x^4 + (0.5x - 5x^2 + 8x^2) - 2

Simplifying the terms inside the parentheses:

20x^4 + (0.5x + 3x^2) - 2

Therefore, the simplified expression is 20x^4 + 0.5x + 3x^2 - 2.

Please note that the above simplification assumes that the expression is meant to be simplified algebraically. If there are any specific instructions or context provided, please let me know and I'll be happy to assist you further.
