Answer:

x₁ = 6

x₂ = 7

Step-by-step explanation:

x² - 2x + 49 = 11x + 7

x² - 2x + 49 - 11x - 7 = 0

x² - 13x + 49 - 7 = 0

x² - 13x + 42 = 0

x² - 6x - 7 + 42 = 0

x*(x - 6) - 7x + 42 = 0

x*(x - 6) - 7(x -6) = 0

(x - 6) * (x - 7) = 0

x - 6 = 0 → x = 6

x - 7 = 0 → x = 7

Hope this helped! :)
