Question
Solve the equation(The real numbers system)
x∈/R
Evaluate
x4=(3x−4)×2
Evaluate
x4=2(3x−4)
Expand the expression
More Steps

Evaluate
2(3x−4)
Apply the distributive property
2×3x−2×4
Multiply the numbers
6x−2×4
Multiply the numbers
6x−8
x4=6x−8
Move the expression to the left side
x4−(6x−8)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x4−6x+8=0
Solution
x∈/R
