Evaluate
−x2×7x−14=0
Multiply
More Steps
Evaluate
−x2×7x
Multiply the terms with the same base by adding their exponents
−x2+1×7
Add the numbers
−x3×7
Use the commutative property to reorder the terms
−7x3
−7x3−14=0
Move the constant to the right-hand side and change its sign
−7x3=0+14
Removing 0 doesn't change the value,so remove it from the expression
−7x3=14
Change the signs on both sides of the equation
7x3=−14
Divide both sides
77x3=7−14
Divide the numbers
x3=7−14
