Full solution

Q. Factor.\newlinev2+18v19v^2 + 18v - 19
  1. Find Numbers: First, we need to find two numbers that multiply to 19-19 and add up to 1818.
  2. List Factors: Let's list the factors of 19-19: 1-1 and 1919, 11 and 19-19.
  3. Identify Multiplication: Now, we see that 1919 and 1-1 multiply to 19-19 and add up to 1818.
  4. Write Middle Term: So, we can write the middle term 18v18v as 19vv19v - v.
  5. Rewrite Expression: Now, rewrite the expression with the new middle terms: v2+19vv19v^2 + 19v - v - 19.
  6. Factor by Grouping: Next, we factor by grouping. Group the first two terms and the last two terms: (v2+19v)(v+19)(v^2 + 19v) - (v + 19).
  7. Factor Common Factor: Factor out the common factor from each group: v(v+19)1(v+19)v(v + 19) - 1(v + 19).
  8. Factor Out Common Factor: Now, we see that (v+19)(v + 19) is a common factor, so we factor it out: (v+19)(v1)(v + 19)(v - 1).
  9. Check Solution: Check the solution by expanding: v + \(19)(v - 11) = v^22 - v + 1919v - 1919 = v^22 + 1818v - 1919.\
