Q. 44. Factor the trinomial completely.\newlinex2+12x+35 x^{2}+12 x+35 \newlineSelect the correct choice below and, if neces\newlineA. x2+12x+35= x^{2}+12 x+35= \square \newlineB. The polynomial is prime.
  1. List Factors of 3535: We list the pairs of factors of 3535: (1,35)(1, 35) and (5,7)(5, 7). We need to find which pair adds up to 1212.
  2. Find Pair Adding to 1212: Checking the pairs, we see that 5+75 + 7 equals 1212. Therefore, the numbers we are looking for are 55 and 77.
  3. Write Trinomial as Product: Now we can write the trinomial as a product of two binomials using the numbers 55 and 77. The factored form is (x+5)(x+7)(x + 5)(x + 7).
  4. Check Factored Form: To ensure there are no mistakes, we can check our factored form by expanding (x+5)(x+7)(x + 5)(x + 7) to see if we get the original trinomial x2+12x+35x^2 + 12x + 35.
  5. Expand and Simplify: Expanding (x+5)(x+7)(x + 5)(x + 7) gives us x2+7x+5x+35x^2 + 7x + 5x + 35, which simplifies to x2+12x+35x^2 + 12x + 35. This matches the original trinomial, confirming that our factored form is correct.
