Question

6 номер, будь ласка нужно до завтра сдать

Answer 1

Ответ:

x²-9x+50/x²-5x = x+1/x-5 + x-5/x, x≠0, x≠5

x²-9x+50/x²-5x - x+1/x-5 - x-5/x = 0

x²-9x+50/x×(x-5) - x+1/x-5 - x-5/x = 0

x²-9x+50-x×(x+1)-(x-5)²/x×(x-5) = 0

x²-9x+50-x²-x-(x-5)²/x×(x-5) = 0

-9x+50-x-(x-5)²/x×(x-5) = 0

-10x+50-(x-5)²/x×(x-5) = 0

-10(x-5)-(x-5)²/x×(x-5) = 0

(x-5)×(-10-(x-5))/x×(x-5) = 0

(x-5)×(-10-x+5)/x×(x-5) = 0

-10-x+5/x = 0

-5-x/x = 0

-5-x = 0

-x = 5

x = -5, x≠0, x≠5

x = -5
