Multiply the terms with the same base by adding their exponents
1728x2+1
Add the numbers
1728x3
1728x3−60x=−2
Move the expression to the left side
1728x3−60x−(−2)=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
1728x3−60x+2=0
Factor the expression
2(6x−1)(144x2+24x−1)=0
Divide both sides
(6x−1)(144x2+24x−1)=0
Separate the equation into 2 possible cases
6x−1=0144x2+24x−1=0

Evaluate
6x−1=0
Move the constant to the right-hand side and change its sign
6x=0+1
Removing 0 doesn't change the value,so remove it from the expression
6x=1
Divide both sides
66x=61
Divide the numbers
x=61
