Evaluate
(x3−2)(4x−3)
To find the roots of the expression,set the expression equal to 0
(x3−2)(4x−3)=0
Separate the equation into 2 possible cases
x3−2=04x−3=0
Solve the equation
More Steps

Evaluate
x3−2=0
Move the constant to the right-hand side and change its sign
x3=0+2
Removing 0 doesn't change the value,so remove it from the expression
x3=2
Take the 3-th root on both sides of the equation
3x3=32
Calculate
x=32
x=324x−3=0
Solve the equation

Evaluate
4x−3=0
Move the constant to the right-hand side and change its sign
4x=0+3
Removing 0 doesn't change the value,so remove it from the expression
4x=3
Divide both sides
44x=43
Divide the numbers
x=43
x=32x=43
