Question
Find the excluded values
u=3
Evaluate
6−2u5
To find the excluded values,set the denominators equal to 0
6−2u=0
Move the constant to the right-hand side and change its sign
−2u=0−6
Removing 0 doesn't change the value,so remove it from the expression
−2u=−6
Change the signs on both sides of the equation
2u=6
Divide both sides
22u=26
Divide the numbers
u=26
