Can you factor this trinomial 9x^+10x+1=

(9x +1)(x +1)

Step-by-step explanation:

The numbers in the binomial factors are factors of 9·1 that have a sum of 10. The factors 9 and 1 are such numbers.

One way to get from this fact to the final factoring is to rewrite the middle term as the sum of two terms:

  9x^2 + 9x + x + 1

Now, you can factor by pairs:

  (9x^2 +9x) +(x +1)

  = 9x(x +1) + 1·(x +1)

  = (9x +1)(x +1)
