Question

x^2+8x+15, factor each trinomial, or state that the trinomial is prime

Answer 1

(x+3) (x+5)

Answer 2

howd you do it

Answer 3

You have given only one trinomial. The trinomial we can discover is solvable by factoring so lets do that. x^2+8+15.

Because this is a trinomial with a degree of 2 we have to place an x in both brackets.

( x + ) ( x+ )

To factor this trinomial we now have to find factors of 15 that when added up equal to the middle term of 8. If we factor 15 it's factors 1, 3, 5, 15 5 and 3 are factors of 15 and add up to 8.

So (x+3)(x+5)
