Find the roots
x1=0,x2=34
Alternative Form
x1=0,x2=1.3˙
Evaluate
(3x4)(3x−4)
To find the roots of the expression,set the expression equal to 0
(3x4)(3x−4)=0
Multiply the terms
3x4(3x−4)=0
Elimination the left coefficient
x4(3x−4)=0
Separate the equation into 2 possible cases
x4=03x−4=0
The only way a power can be 0 is when the base equals 0
x=03x−4=0
Solve the equation

Evaluate
3x−4=0
Move the constant to the right-hand side and change its sign
3x=0+4
Removing 0 doesn't change the value,so remove it from the expression
3x=4
Divide both sides
33x=34
Divide the numbers
x=34
x=0x=34
