How do you factor #x^2+14x+45#?
In order to the trinomial
Begin by finding the factors for the first term
Place those factors as the first term in each parenthesis
Since both signs of the trinomial are positive you will be adding the factors and both signs will be positive.
Now determine the factors of the third term
We need the factors that will add up to the middle term
Place these factors as the second term in each of the parenthesis.
