Rewrite the expression
(5−x)x
Multiply the terms
x(5−x)
x(5−x)=0
Separate the equation into 2 possible cases
x=05−x=0
Solve the equation
More Steps

Evaluate
5−x=0
Move the constant to the right-hand side and change its sign
−x=0−5
Removing 0 doesn't change the value,so remove it from the expression
−x=−5
Change the signs on both sides of the equation
x=5
x=0x=5
Solution
x1=0,x2=5
