The square of x² + 16x + 63 = 0 is given by (x + 8)² = 127.
Given that,
x² + 16x + 63 = 0
To complete the square of above given equation.
Power is the degree of values that are mentioned at the superscript of the value.
Here,
x² + 16x + 63 = 0
Dividing the coefficient of x by 2, and adding and subtracting the square of the quotient.
x² + 16x + 64 - 64 - 63 = 0
(x + 8)² = 127
Thus, the square of x² + 16x + 63 = 0 is given by (x + 8)² = 127.
