Q. Factor completely.\newline180x10125x2 180 x^{10}-125 x^{2} \newlineAnswer:
  1. Identify GCF: Identify the greatest common factor (GCF) of the terms 180x10180x^{10} and 125x2125x^{2}. The GCF of the numerical coefficients 180180 and 125125 is 55. The GCF of the variable terms x10x^{10} and x2x^{2} is x2x^{2}, since x2x^{2} is the highest power of xx that divides both terms. Therefore, the GCF of the entire expression is 125x2125x^{2}00.
  2. Factor out GCF: Factor out the GCF from the expression.\newline180x10125x2=5x2(36x825)180x^{10} - 125x^{2} = 5x^{2}(36x^{8} - 25)
  3. Find further factorization: Look for further factorization within the parentheses.\newlineThe expression inside the parentheses, 36x82536x^{8} - 25, is a difference of squares since 36x836x^{8} is a perfect square (6x4)2(6x^{4})^2 and 2525 is a perfect square (5)2(5)^2.\newlineThe difference of squares can be factored as (a2b2)=(a+b)(ab)(a^2 - b^2) = (a + b)(a - b).
  4. Apply difference of squares: Apply the difference of squares factorization to the expression inside the parentheses. 36x825=(6x4)2(5)2=(6x4+5)(6x45)36x^{8} - 25 = (6x^{4})^2 - (5)^2 = (6x^{4} + 5)(6x^{4} - 5)
  5. Combine with GCF: Combine the GCF with the factored form of the expression inside the parentheses.\newline5x2(36x825)=5x2(6x4+5)(6x45)5x^{2}(36x^{8} - 25) = 5x^{2}(6x^{4} + 5)(6x^{4} - 5)
