For problems 116-121, factor each trinomial and assume that all variables that appear as exponents represent positive integers.
The given trinomial , where the exponent is a positive integer.
To factor trinomials of the form , we use the following procedure:
Let us consider a product .
Using the distributive property of multiplication, we get
From the above, we find that the product of yields a trinomial of the form .
It must be noted that the middle term is the sum of and and the last term is the product of and .
These two relationships can be used for factoring trinomials of the form .
Given expression: .
We need to complete the following with two integers whose sum is and whose product is
