Full solution

Q. Factor.\newline16u22516u^2 - 25
  1. Approach Determination: Determine the approach to factor 16u22516u^2 - 25. We can observe that the expression is a difference of squares, which can be factored using the formula a2b2=(ab)(a+b)a^2 - b^2 = (a - b)(a + b).
  2. Form Identification: Identify 16u22516u^2 - 25 in the form of a2b2a^2 - b^2. 16u216u^2 can be written as (4u)2(4u)^2 because 4u×4u=16u24u \times 4u = 16u^2. 2525 can be written as 525^2 because 5×5=255 \times 5 = 25. So, 16u22516u^2 - 25 is in the form of (4u)252(4u)^2 - 5^2.
  3. Formula Application: Apply the difference of squares formula to factor the expression.\newlineUsing the formula a2b2=(ab)(a+b)a^2 - b^2 = (a - b)(a + b), we substitute aa with 4u4u and bb with 55.\newline(4u)252=(4u5)(4u+5)(4u)^2 - 5^2 = (4u - 5)(4u + 5).
  4. Final Factored Form: Write the final factored form.\newlineThe factored form of 16u22516u^2 - 25 is (4u5)(4u+5)(4u - 5)(4u + 5).
