Type your math problem... 7x-14x^2=0

Question

Solve the quadratic equation

Solve by factoring

Solve using the quadratic formula

Solve by completing the square

x_{1} = 0, x_{2} = \frac{1}{2}

Alternative Form

x_{1} = 0, x_{2} = 0.5

Evaluate

7 x - 14 x^{2} = 0

Factor the expression

More Steps

Evaluate

7 x - 14 x^{2}

Rewrite the expression

7 x - 7 x \times 2 x

Factor out 7 x from the expression

7 x (1 - 2 x)

7 x (1 - 2 x) = 0

When the product of factors equals 0,at least one factor is 0

1 - 2 x = 0 7 x = 0

Solve the equation for x

More Steps

Evaluate

1 - 2 x = 0

Move the constant to the right-hand side and change its sign

- 2 x = 0 - 1

Removing 0 doesn't change the value,so remove it from the expression

- 2 x = - 1

Change the signs on both sides of the equation

2 x = 1

Divide both sides

\frac{2 x}{2} = \frac{1}{2}

Divide the numbers

x = \frac{1}{2}

x = \frac{1}{2} 7 x = 0

Solve the equation for x

x = \frac{1}{2} x = 0

Solution

x_{1} = 0, x_{2} = \frac{1}{2}

Alternative Form

x_{1} = 0, x_{2} = 0.5
