Full solution

Q. Factor.\newline2h2+9h+102h^2 + 9h + 10
  1. Identify coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 2h2+9h+102h^2 + 9h + 10 by comparing it to the standard form ax2+bx+cax^2 + bx + c.\newlinea=2a = 2, b=9b = 9, c=10c = 10
  2. Find two numbers: Find two numbers that multiply to aca*c (210=202*10 = 20) and add up to bb (99).\newlineThe numbers 55 and 44 multiply to 2020 and add up to 99.
  3. Rewrite middle term: Rewrite the middle term, 9h9h, using the two numbers found in the previous step: 5h5h and 4h4h. \newline2h2+9h+102h^2 + 9h + 10 becomes 2h2+5h+4h+102h^2 + 5h + 4h + 10.
  4. Group terms: Group the terms into two pairs: 2h2+5h2h^2 + 5h and 4h+104h + 10.
  5. Factor out common factor: Factor out the greatest common factor from each pair.\newlineFrom the first pair (2h2+5h)(2h^2 + 5h), factor out hh: h(2h+5)h(2h + 5).\newlineFrom the second pair (4h+10)(4h + 10), factor out 22: 2(2h+5)2(2h + 5).
  6. Write final expression: Notice that both groups now contain the common factor (2h+5)(2h + 5).\newlineWrite the expression as (h+2)(2h+5)(h + 2)(2h + 5).
