Q. We want to factor the following expression:\newlinex325x^{3}-25\newlineWhich pattern can we use to factor the expression?\newlineUU and VV are either constant integers or single-variable expressions.\newlineChoose 11 answer:\newline(A) (U+V)2(U+V)^{2} or (UV)2(U-V)^{2}\newline(B) (U+V)(UV)(U+V)(U-V)\newline(C) We can't use any of the patterns.
  1. Identify expression: Identify the expression to be factored.\newlineThe expression given is x325x^3 - 25. We need to find a pattern to factor this expression.
  2. Recognize pattern: Recognize the pattern applicable for the expression.\newlineThe expression x325x^3 - 25 can be seen as a difference of cubes, where x3x^3 is a cube and 2525 can be written as 535^3. Therefore, the expression can be rewritten as x353x^3 - 5^3. The pattern for factoring a difference of cubes is (U3V3)=(UV)(U2+UV+V2)(U^3 - V^3) = (U - V)(U^2 + UV + V^2), where UU and VV are either constant integers or single-variable expressions.
  3. Apply pattern: Apply the pattern to factor the expression.\newlineUsing the pattern for the difference of cubes, we can factor x353x^3 - 5^3 as follows:\newlineLet U=xU = x and V=5V = 5, then\newline(x353)=(x5)(x2+5x+25)(x^3 - 5^3) = (x - 5)(x^2 + 5x + 25).
