Answer 1

7)25+8m/m²-25 - m+2/5-m × m/m+5

25+8m/m²-25 - m×(m+2)/(5-m)×(m+5)

25+8m/m²-25 - m²+2m/25-m²

25+8m/m²-25 - m²+2m/(-m²-25)

25+8m/m²-25 + m²+2m/m²-25

25+8m+m²+2m/m²-25

25+10m+m²/(m-5)×(m+5)

(m+5)²/(m-5)×(m+5)

5+m/m-5

8) 6-x²/x²-6 + x+6/x-6 = 3/x

6-x²/x²-6 + x+6/x-6 = 3/x, x≠0 x≠6

6-x²/x²-6 + x+6/x-6 - 3/x = 0

6-x²/x×(x-6) + x+6/x-6 - 3/x = 0

6-x²+x×(x+6)-3(x-6)/x×(x-6) = 0

6-x²+x²+6x-3x+18/x×(x-6) = 0

24+3x/x×(x-6) = 0

24+3x = 0

3x = -24

х=-8, х≠0, х≠6

x= -8
