Subtract the numbers
−x3
−x3−294=0
Move the constant to the right-hand side and change its sign
−x3=0+294
Removing 0 doesn't change the value,so remove it from the expression
−x3=294
Change the signs on both sides of the equation
x3=−294
Take the 3-th root on both sides of the equation
3x3=3−294
Calculate
x=3−294
