Simplify the expression. √8 – √50

To simplify the expression √8 – √50, we can break down each square root into simpler terms.

First, let’s simplify √8:

√8 = √(4 * 2) = √4 * √2 = 2√2

Next, let’s simplify √50:

√50 = √(25 * 2) = √25 * √2 = 5√2

Now, we can substitute these back into the original expression:

√8 – √50 = 2√2 – 5√2

Combining the like terms:

(2 – 5)√2 = -3√2

So, the simplified expression is -3√2.

The correct answer is -3√2.
