Question

0.5х²+2х-2.50

Answer 1

Вторая скобка тоже квадратная, не очень красиво получилась

Answer 2

The expression you've provided is a quadratic polynomial. It can be simplified as follows:

0.5x² + 2x - 2.50

To make it look more standard, let's multiply the whole expression by 2 to remove the decimal coefficient:

2 * (0.5x² + 2x - 2.50)

Now, distribute the 2 across the terms:

1x² + 4x - 5

So, the simplified form of the expression is:

x² + 4x - 5
