Hey Tanya — ready when you are. Here is the solution for question 3 (i): 3. Simplify. 3 (i): (x^2 - 5)(x + 5) + 25 Step 1: Multiply the binomials (x^2 - 5) and (x + 5) using the distributive property (FOIL method). (x^2 - 5)(x + 5) = x^2(x) + x^2(5) - 5(x) - 5(5) = x^3 + 5x^2 - 5x - 25 Step 2: Add the constant 25 to the result from Step 1. x^3 + 5x^2 - 5x - 25 + 25 Step 3: Combine the constant terms. = x^3 + 5x^2 - 5x What's next?
