Answer:
Step 1: x^2 + 8x + 15 + 1 = 0 + 1
Step 2: x^2 + 8x + 16 = 1
Step 3: (x + 4)^2 = 1
Step-by-step explanation:
You want the constant on the left to be the square of half the x-coefficient.
(8/2)^2 = 4^2 = 16
You already have a constant that is 15, so you need to add 1 to both sides of the equation. That is the <em>Step 1</em> shown here. <em>Step 2</em> is simplifying the result of <em>Step 1</em>. <em>Step 3</em> is rewriting the trinomial as the square of a binomial.
