Q. 299 - Intermediate Algebra

Question

In the following exercises, solve.
$\sqrt{2u-3}+2=0$

Step-by-Step Solution

Answer

The given equation has no solution.

Step 1. Given information.

The given equation is:

$\sqrt{2u-3}+2=0$

Step 2. Solve the equation.

The given equation can be written as:

$\sqrt{2u-3}=-2$

For all real value of $x,\sqrt{x}\ge 0$.

In other words, a radical value cannot be equal to a negative value.

So, $\sqrt{2u-3}\ne -2$ for any real value of $u$.

Step 3. Conclusion.

The given equation has no solution.
