To simplify the expression ((x - 2)(2x + 4)), you can use the distributive property (also known as the FOIL method for binomials). Multiply each term in the first binomial by each term in the second binomial:
[ x \cdot 2x + x \cdot 4 - 2 \cdot 2x - 2 \cdot 4. ]
This results in (2x^2 + 4x - 4x - 8). The (4x) and (-4x) cancel each other out, leaving you with the simplified expression (2x^2 - 8).

Simplify (1x2-2x plus 4) plus (2x plus 1)-(x2 plus 5)?
To simplify the expression ((1x^2 - 2x + 4) + (2x + 1) - (x^2 + 5)), first combine like terms. The (x^2) terms give (1x^2 - 1x^2 = 0). The (x) terms yield (-2x + 2x = 0), and the constant terms combine to (4 + 1 - 5 = 0). Thus, the simplified expression is (0).
