How do you do this question?

Answer:
C) 5 sin⁻¹(x − 1) + C
Step-by-step explanation:
∫ 10 / √(8x − 4x²) dx
Simplify.
∫ 5 / √(2x − x²) dx
Complete the square.
∫ 5 / √(-(x² − 2x) dx
∫ 5 / √(-(x² − 2x + 1 − 1) dx
∫ 5 / √(-(x² − 2x + 1) + 1) dx
∫ 5 / √(-(x − 1)² + 1) dx
∫ 5 / √(1 − (x − 1)²) dx
Integrate using a table.
5 sin⁻¹(x − 1) + C
