Step-by-step explanation:
To begin, get everything but the x terms on one side of the equation by subtracting the 62. That gives us
Next, take half the linear term, square it, and add it to both sides. Our linear term is 16. Half of 16 is 8, and 8 squared is 6, so add 64 to both sides:
The reason we do this is to get a perfect square binomial on the left, which looks like this:
x + 8 = 3 and x + 8 = -3. Solving each of these equations gives you your 2 solutions:
x = -5 and x = -11
