Answer:
Step-by-step explanation:
We're going to try two things here.
First an example
x^2 + 10x + 25
If you divide the linear factor by 2 and square the result, you get the last number (25)
The pattern of a trinomial is
x^2 + 2b x + b^2
The factors are
(x + b)(x+ b)
Just divide the linear term by 2
