Solution
4\left(2x-5\right)
Show Solutions
Find the roots
x=\frac{5}{2}
Alternative Form
x=2.5
Evaluate
8x-20
To find the roots of the expression,set the expression equal to 0
8x-20=0
Move the constant to the right-hand side and change its sign
8x=0+20
Removing 0 doesn't change the value,so remove it from the expression
8x=20
Divide both sides
\frac{8x}{8}=\frac{20}{8}
Divide the numbers
x=\frac{20}{8}
Solution
x=\frac{5}{2}
Alternative Form
x=2.5
