To solve the expression (2x+4)(x-1), we can use the distributive property of multiplication, which states that a(b + c) = ab + ac.
(2x+4)(x-1)
= 2x(x-1) + 4(x-1) (distributing the first term)
= 2x^2 - 2x + 4x - 4 (using the distributive property again)
= 2x^2 + 2x - 4
Therefore, (2x+4)(x-1) simplifies to 2x^2 + 2x - 4.
