Step-by-step explanation:
Answer:
x = 5 ±
Step-by-step explanation:
Given
x² - 10x + 26 = 8 ( subtract 26 from both sides )
x² - 10x = - 18
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 18 + 25
(x - 5)² = 7 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
x = 5 ± ← exact solutions
