by cross multiplication,
300x - 300(x-5) / x(x-5) =2
300x-300x+1500/x^2-5x =2
1500=2x^2-10x
divide by 2 on both sides .,,
750=x^2-5x
==>x^2-5x-750=0
x= -b(+r-) √b^2-4ac / 2a
=5(+r-) √25+3000 / 2
=5(+r-) √3025 / 2
=5(+r-) 55 / 2
x=30 ,-25
300x - 300(x-5) / x(x-5) =2
300x-300x+1500/x^2-5x =2
1500=2x^2-10x
divide by 2 on both sides .,,
750=x^2-5x
==>x^2-5x-750=0
x= -b(+r-) √b^2-4ac / 2a
=5(+r-) √25+3000 / 2
=5(+r-) √3025 / 2
=5(+r-) 55 / 2
x=30 ,-25
