Solution
2\left(x-9\right)
Show Solutions
Find the roots
x=9
Evaluate
2x-18
To find the roots of the expression,set the expression equal to 0
2x-18=0
Move the constant to the right-hand side and change its sign
2x=0+18
Removing 0 doesn't change the value,so remove it from the expression
2x=18
Divide both sides
\frac{2x}{2}=\frac{18}{2}
Divide the numbers
x=\frac{18}{2}
