Need help with exercises. Equations etc.

  • #1
√x2 + 1 + √x2 – 2x + 3 = 3

│ x-4 │ - │ 2–0,5x│ ≤ 3

│5- x2-6 │= x2-5x-6

x2-2x+3 : x2-4x+3 > -2

First, show us the work you have done to solve these equations and inequalities. We're willing to help, but not willing to do your work for you.

Second, you have several expressions written as x2. Is this supposed to be x2? When you're posting something, click Go Advanced, and the menu bar just above the text entry area has a button that inserts the tags for exponents. Use this button to write exponents.
