Multiply the terms
4×53(x−1)
Multiply the terms
54×3(x−1)
Multiply the terms
512(x−1)
65x3=512(x−1)
Cross multiply
5x3×5=6×12(x−1)
Simplify the equation
25x3=6×12(x−1)
Simplify the equation
25x3=72(x−1)
Expand the expression
More Steps

Evaluate
72(x−1)
Apply the distributive property
72x−72×1
Any expression multiplied by 1 remains the same
72x−72
25x3=72x−72
Move the expression to the left side
25x3−(72x−72)=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
25x3−72x+72=0
Solution
x≈−2.067174
