The solution to the given quadratic expression using the completing the square is x = ±√10 +8
Completing the square method
This is a method of factoring quadratic expression. Given the quadratic function.
x^2 − 16x + 54 = 0
Subtract 54 from both sides
x^2 − 16x = -54
Complete the square
x^2 -16x +8^2 = -54 + 64
(x-8)² = 10
x - 8 = ±√10
x = ±√10 +8
Hence the solution to the given quadratic expression using the completing the square is x = ±√10 +8
