Full solution

Q. Factor.\newlinep2+20p+19p^2 + 20p + 19
  1. Identify Coefficients: Identify the coefficients for p2p^2, pp, and the constant term in the quadratic expression p2+20p+19p^2 + 20p + 19. The quadratic expression is in the form p2+bp+cp^2 + bp + c, where bb is the coefficient of pp, and cc is the constant term. For p2+20p+19p^2 + 20p + 19, b=20b = 20 and c=19c = 19.
  2. Find Multiplying Numbers: Find two numbers that multiply to give c(19)c (19) and add up to give b(20)b (20). We need to find two numbers mm and nn such that m×n=19m \times n = 19 and m+n=20m + n = 20. Since 1919 is a prime number, the only factors of 1919 are 11 and 1919 itself. b(20)b (20)00 and b(20)b (20)11, so the numbers we are looking for are 11 and 1919.
  3. Write Factored Form: Write the factored form of the quadratic expression using the numbers found in the previous step.\newlineThe factored form will be (p+m)(p+n)(p + m)(p + n), where mm and nn are the numbers found.\newlineSubstitute m=1m = 1 and n=19n = 19 into the factored form to get (p+1)(p+19)(p + 1)(p + 19).
