The expression in the image is:

$\sqrt{\frac{(3x - 3)(2x^2 + 14)}{(3x^2 + 4x + 15)}}$

Let's simplify and analyze the expression step by step:

Step 1: Simplify the numerator

The numerator is: $(3x - 3)(2x^2 + 14)$ You can factor out the constants: $3(x - 1)(2(x^2 + 7)) = 6(x - 1)(x^2 + 7)$

Step 2: Review the denominator

The denominator is: $3x^2 + 4x + 15$ This quadratic expression cannot be easily factored, so it remains as is.

Step 3: Simplify the whole expression

Now, substitute the simplified numerator: $\sqrt{\frac{6(x - 1)(x^2 + 7)}{3x^2 + 4x + 15}}$

Since no further simplification is possible between the numerator and denominator, this is the simplest form of the expression.
