Hey Sibusiso, good to see you again. Step 1: Distribute the terms in the expression. Multiply x by each term inside the first parenthesis, and multiply -2 by each term inside the second parenthesis. x(x+4) - 2(x-D) = (x · x) + (x · 4) - (2 · x) - (2 · (-D)) = x^2 + 4x - 2x + 2D Step 2: Combine like terms. Combine the terms with x. x^2 + (4x - 2x) + 2D = x^2 + 2x + 2D The simplified expression is: x^2 + 2x + 2D Send me the next one 📸
