Type your math problem... sqrt(5x-2)

Question

Find the roots

x = \frac{2}{5}

Alternative Form

x = 0.4

Evaluate

5 x - 2

To find the roots of the expression,set the expression equal to 0

5 x - 2 = 0

Find the domain

More Steps

Evaluate

5 x - 2 \geq 0

Move the constant to the right side

5 x \geq 0 + 2

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

5 x \geq 2

Divide both sides

\frac{5 x}{5} \geq \frac{2}{5}

Divide the numbers

x \geq \frac{2}{5}

5 x - 2 = 0, x \geq \frac{2}{5}

Calculate

5 x - 2 = 0

The only way a root could be 0 is when the radicand equals 0

5 x - 2 = 0

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

5 x = 0 + 2

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

5 x = 2

Divide both sides

\frac{5 x}{5} = \frac{2}{5}

Divide the numbers

x = \frac{2}{5}

Check if the solution is in the defined range

x = \frac{2}{5}, x \geq \frac{2}{5}

Solution

x = \frac{2}{5}

Alternative Form

x = 0.4
