Full solution

Q. Factor.\newline9p2+30p+259p^2 + 30p + 25
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is 9p2+30p+259p^2 + 30p + 25. Here, the coefficient of p2p^2 (a)(a) is 99, the coefficient of pp (b)(b) is 3030, and the constant term (c)(c) is 2525.
  2. Find Multiplying Numbers: Determine two numbers that multiply to acac (9×25=2259 \times 25 = 225) and add up to bb (3030).\newlineWe need to find two numbers that multiply to 225225 and add up to 3030. The numbers 1515 and 1515 satisfy both conditions because 15×15=22515 \times 15 = 225 and 15+15=3015 + 15 = 30.
  3. Write Middle Term: Write the middle term 30p30p as the sum of two terms using the numbers found in the previous step.\newlineWe can express 30p30p as 15p+15p15p + 15p. So, the expression becomes 9p2+15p+15p+259p^2 + 15p + 15p + 25.
  4. Factor by Grouping: Factor by grouping.\newlineWe group the terms as (9p2+15p)+(15p+25)(9p^2 + 15p) + (15p + 25) and factor out the common factors from each group. From the first group, we can factor out 3p3p, and from the second group, we can factor out 55.\newlineThis gives us 3p(3p+5)+5(3p+5)3p(3p + 5) + 5(3p + 5).
  5. Factor Common Binomial: Factor out the common binomial factor.\newlineBoth terms have a common binomial factor of (3p+5)(3p + 5). Factoring this out, we get (3p+5)(3p+5)(3p + 5)(3p + 5) or (3p+5)2(3p + 5)^2.
