Multiply the terms
x2(x−1)×25(1−x)
Use the commutative property to reorder the terms
25x2(x−1)(1−x)
Multiply the terms
25x2(−(x−1)2)
Use the commutative property to reorder the terms
x2(−25)(x−1)2
Use the commutative property to reorder the terms
−25x2(x−1)2
−25x2(x−1)2=0
Change the sign
25x2(x−1)2=0
Elimination the left coefficient
x2(x−1)2=0
Separate the equation into 2 possible cases
x2=0(x−1)2=0
The only way a power can be 0 is when the base equals 0
x=0(x−1)2=0
Solve the equation

Evaluate
(x−1)2=0
The only way a power can be 0 is when the base equals 0
x−1=0
Move the constant to the right-hand side and change its sign
x=0+1
Removing 0 doesn't change the value,so remove it from the expression
x=1
x=0x=1
Solution
x1=0,x2=1
