Question

У= (2-х)(х+4) все под корнем

Answer 1

$\sqrt{y=(2-x)(x+4)} \sqrt{y=2x+8-x^2-4x} \sqrt{y} = \sqrt{-(x^2)+2x+4x}$

Answer 2

To simplify the expression √((2-x)(x+4)), we can first expand the expression inside the square root and then try to find any possible simplifications. Here's the step-by-step process:

Step 1: Expand the expression inside the square root. (2 - x)(x + 4) = 2x + 8 - x^2 - 4x

Step 2: Combine like terms. 2x - x^2 - 4x + 8 = -x^2 - 2x + 8

Step 3: Write the simplified expression under the square root. √((-x^2 - 2x + 8))

The expression √((-x^2 - 2x + 8)) is the simplified form of the original expression (2-x)(x+4) under the square root. However, it cannot be simplified further without additional information or context.
