Answer:

6x²+4x

Step-by-step explanation:

The given expressions are 3x²- 4x-4 and 3x²+8x+4.

We need to add these two expressions.

3x²- 4x-4 + 3x²+8x+4 = 3x² + 3x² -4x+8x-4+4

= 6x²+4x

On adding the given expressions, we get the value as 6x²+4x. Hence, the sum of the given expressions is equal to 6x²+4x

$2x + 44 = 5x + 38$
$5x - 2x = 3x$
$44 = 3x + 38$
$44 - 38 = 6$
$6 = 3x$
$2 = x$
