Solve the equation
x=−1
Evaluate
−x2×2x−2=0
Multiply
More Steps
Evaluate
−x2×2x
Multiply the terms with the same base by adding their exponents
−x2+1×2
Add the numbers
−x3×2
Use the commutative property to reorder the terms
−2x3
−2x3−2=0
Move the constant to the right-hand side and change its sign
−2x3=0+2
Removing 0 doesn't change the value,so remove it from the expression
−2x3=2
Change the signs on both sides of the equation
2x3=−2
Divide both sides
22x3=2−2
Divide the numbers
x3=2−2
