Question
Find the roots
x=3
Evaluate
x−3
To find the roots of the expression,set the expression equal to 0
x−3=0
Find the domain
More Steps
Evaluate
x−3≥0
Move the constant to the right side
x≥0+3
Removing 0 doesn't change the value,so remove it from the expression
x≥3
x−3=0,x≥3
Calculate
x−3=0
The only way a root could be 0 is when the radicand equals 0
x−3=0
Move the constant to the right-hand side and change its sign
x=0+3
Removing 0 doesn't change the value,so remove it from the expression
x=3
Check if the solution is in the defined range
x=3,x≥3
Solution
x=3
