2x^2+14+8 (trinomial)
factor by greatest common factor which happens to be 2
2(x^2+7+4) This is the factored form
Check if there are things that can still be factored. In the example, there is none.
Multiply using the Distributive Method to check if your factors are correct
(2(x^2))+(2(7))+(2(4))
4x^2+14+8
You got the right factors.
Note: ^ is for exponents
