If each expression under the square root is greater than or equal to 0, what is x2−6x+9√+2−x√+x−3x2−6x+9+2−x+x−3?

 is the final answer

Step-by-step explanation:

If each expression under the square root is greater than or equal to 0, what is x2−6x+9−−−−−−−−−√+2−x−−−−√+x−3x2−6x+9+2−x+x−3?

can be rearranged as thus

factorizing x^2-6x+9

..................1

take note that

Ix-3I+...................2

Ix-3I is equal to -(x-3)...............3

Now, as the expressions under the square roots are greater than or equal to zero than 2−x≥0

2−x≥0

--> -x≤-2

x≤2.

substituting  3 into the equation 2

-(x-3)++x-3

 is the final answer

-4
