Question

Resolución de ecuaciones de la forma 7x2+14x=0

Answer 1

7×2+4x=0

14+14x=0

14x=-14

X=-14/14

X=-1

Answer 2

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
