Find the roots
x1=23,x2=4
Alternative Form
x1=1.5,x2=4
Evaluate
(x−4)2(3−2x)3
To find the roots of the expression,set the expression equal to 0
(x−4)2(3−2x)3=0
Separate the equation into 2 possible cases
(x−4)2=0(3−2x)3=0
Solve the equation
More Steps

Evaluate
(x−4)2=0
The only way a power can be 0 is when the base equals 0
x−4=0
Move the constant to the right-hand side and change its sign
x=0+4
Removing 0 doesn't change the value,so remove it from the expression
x=4
x=4(3−2x)3=0
Solve the equation

Evaluate
(3−2x)3=0
The only way a power can be 0 is when the base equals 0
3−2x=0
Move the constant to the right-hand side and change its sign
−2x=0−3
Removing 0 doesn't change the value,so remove it from the expression
−2x=−3
Change the signs on both sides of the equation
2x=3
Divide both sides
22x=23
Divide the numbers
x=23
x=4x=23
