Full solution

Q. Factor.\newline2f2+9f+92f^2 + 9f + 9
  1. Identify coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 2f2+9f+92f^2 + 9f + 9 by comparing it to the standard form ax2+bx+cax^2 + bx + c.a=2a = 2, b=9b = 9, c=9c = 9
  2. Find two numbers: Find two numbers that multiply to aca*c (29=182*9 = 18) and add up to bb (99).\newlineThe numbers that satisfy these conditions are 33 and 66, since 36=183*6 = 18 and 3+6=93+6 = 9.
  3. Rewrite middle term: Rewrite the middle term 9f9f using the two numbers found in the previous step.\newline2f2+9f+92f^2 + 9f + 9 can be rewritten as 2f2+3f+6f+92f^2 + 3f + 6f + 9.
  4. Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together.\newline(2f2+3f)+(6f+9)(2f^2 + 3f) + (6f + 9)
  5. Factor out common factor: Factor out the greatest common factor from each group.\newlinef(2f+3)+3(2f+3)f(2f + 3) + 3(2f + 3)
  6. Final factored form: Since both groups contain the common factor (2f+3)(2f + 3), factor this out.(f+3)(2f+3)(f + 3)(2f + 3) is the factored form of the quadratic expression.
