Full solution

Q. Factor.\newline25h2425h^2 - 4
  1. Determine factoring technique: Determine the appropriate factoring technique for 25h2425h^2 - 4. Since we have a difference of squares, we can use the formula a2b2=(ab)(a+b)a^2 - b^2 = (a - b)(a + b).
  2. Identify perfect squares: Identify the terms in the expression 25h2425h^2 - 4 as perfect squares.\newline25h225h^2 can be written as (5h)2(5h)^2 because 5h×5h=25h25h \times 5h = 25h^2.\newline44 can be written as 222^2 because 2×2=42 \times 2 = 4.\newlineSo, 25h2425h^2 - 4 is in the form of a2b2a^2 - b^2 where a=5ha = 5h and 25h225h^200.
  3. Apply difference of squares formula: 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 get:\newline(5h)222=(5h2)(5h+2)(5h)^2 - 2^2 = (5h - 2)(5h + 2).
