Full solution

Q. Find the product. Simplify your answer.\newline(y4)(y+4)(y - 4)(y + 4)
  1. Identify special case: Identify the special case for the product (y4)(y+4)(y - 4)(y + 4). This product is in the form of (ab)(a+b)(a - b)(a + b), which is a difference of squares. Special case: (ab)(a+b)=a2b2(a - b)(a + b) = a^2 - b^2
  2. Identify values of aa and bb: Identify the values of aa and bb. Compare (y4)(y+4)(y - 4)(y + 4) with (ab)(a+b)(a - b)(a + b). a=ya = y b=4b = 4
  3. Apply difference of squares formula: Apply the difference of squares formula to expand (y4)(y+4)(y - 4)(y + 4).\newline(ab)(a+b)=a2b2(a - b)(a + b) = a^2 - b^2\newline(y4)(y+4)=y242(y - 4)(y + 4) = y^2 - 4^2
  4. Simplify expression: Simplify y242y^2 - 4^2. \newliney242=y216y^2 - 4^2 = y^2 - 16
