Answer 2

I'm sorry, but there seems to be an error in the equation you provided. Let's break it down and identify the issue.

The equation you wrote is: 0,5(х-6)(х-5) = 0,5х²-5,5х+15

However, the correct expanded form of the left side of the equation should be: 0,5х²-8х+15

To clarify, let's go through the steps of expanding the left side of the equation:

0,5(х-6)(х-5) = 0,5 * (х * х - х * 5 - 6 * х + 6 * 5) = 0,5 * (х² - 5х - 6х + 30) = 0,5 * (х² - 11х + 30) = 0,5х² - 5,5х + 15

As you can see, the expanded form of the left side does not match the right side of the equation. Please double-check your equation or provide more information if there is any specific question or clarification you need.
