Answer

$2x^2+7x-4$

Work Step by Step

We start with the given expression: $(x+4)(2x-1)$ To simplify an algebraic expression, we must eliminate any parentheses and combine like terms. We use the distributive property to multiply the binomials and remove the parentheses: $2x^2+4(2x)-1(x)-1(4)$ We multiply each term to simplify them: $2x^2+8x-x-4$ We combine the like terms by subtracting: $2x^2+7x-4$
