$-4x^2+8x$
We start with the given expression: $-4x(x-2)$ To simplify an algebraic expression, we must eliminate any parentheses and combine like terms. To eliminate parentheses, we apply the distributive property: $-4x*x-2*-4x$ We multiply each term: $-4x^2+8x$ Since there are no like terms, the expression has been simplified.
