Step-by-step explanation:-

(I)

x²-5x+6/x²-9

⇛[(x*x) - (x+x+x+x+x) + 3+2]/[(x*x) - (3+3+3)]

⇛[1-5x + 2]/-6

⇛[1-5x]/-3 Ans.

(ii)

2x - 6x²/4x² + 10x

⇛[(x+x) - 3*3(x*x)]/[2*2(x*x) + 5+5(x)]

⇛[2x - 6x²]/[4x²+10x]

⇛[2x - 3x²]/2x² + 10x]

⇛[1x - 3x²]/2x² + 5x]

⇛[x - 3x²-2x²]/5x

⇛[x - 1x²]/5x

⇛[x - x²]/5x

⇛x/5x

⇛x/(x+x+x+x+x)

⇛4x Ans.

(iii)

x+4/x²+6x+8

⇛[x + 2*2]/[(x*x)+(x+x+x+x+x+x) + 2*2*2*2]

⇛x/[(x*x) + (x+x+x+x+x+x) + 2*2]

⇛x + 6x + 4

⇛7x + 4

⇛x = 7/4 Ans.

(iv)

4x²-24/x²-12x+36

⇛[2*2(x*x) - 2*2*2*3]/[(x*x)-(x+x+x+x+x+x+x+x+x+x+x) + 2*3*3*2]

⇛[2*2 - 2*2*2*3]/[-(x+x+x+x+x+x+x+x+x+x+x+x)] + 2*3*3*2]

⇛[-2*2*2]/[(x+x+x+x+x+x+x+x+x+x+x+x)+3]

⇛24/12x + 3

8/12x Ans.

(v)

x-2/x³-8

⇛[x-2]/[x*x*x - 2*2*2]

⇛-1 /x²- 4 Ans.

(vi)

x²-7x+10/x²-4x+4

⇛[x*x - x+x+x+x+x+x+x + 2*5]/[x*x - x+x+x+x + 2*2]

⇛[-x+x+x+x+x+x+x + 2*5]/[-x+x+x+x + 2*2]

⇛[-x+x+x+2*5]/[2*2]

⇛[-x+x+x + 5]/3

⇛[x+5]/5 Ans.
