Solve x^(2) 20=4x

Evaluate

x^{2} \times 20 = 4 x

Use the commutative property to reorder the terms

20 x^{2} = 4 x

Move the expression to the left side

20 x^{2} - 4 x = 0

Factor the expression

More Steps

4 x (5 x - 1) = 0

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

5 x - 1 = 0 4 x = 0

Solve the equation for x

More Steps

x = \frac{1}{5} 4 x = 0

Solve the equation for x

x = \frac{1}{5} x = 0

Solution

x_{1} = 0, x_{2} = \frac{1}{5}

Alternative Form

x_{1} = 0, x_{2} = 0.2
