Answer:

(x + 8)^2 = 1.

Step-by-step explanation:

We use the identity x^2 + ax + b =  (x + a/2)^2 - (a/2)^2 + b.

x^2 + 16x + 63 = 0

(x +16/2)^2 - (16/2)^2 + 63 = 0

(x + 8)^2 - 64 + 63 = 0

(x + 8)^2 - 1 = 0

(x + 8)^2 = 1.

D = 15(t + 1)

Explanation:

The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.
