Simplifying

7x2 + - 14x = 0

Reorder the terms : - 14x + 7x2 = 0

Solving - 14x + 7x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '7x'.

7x( - 2 + x) = 0

Ignore the factor 7.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve :

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Subproblem 2

Set the factor '( - 2 + x)' equal to zero and attempt to solve :

Simplifying - 2 + x = 0

Solving - 2 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

- 2 + 2 + x = 0 + 2

Combine like terms : - 2 + 2 = 0

0 + x = 0 + 2

x = 0 + 2

Combine like terms : 0 + 2 = 2

x = 2

Simplifying

x = 2.
