both

also, add some brackets so the q's a bit clearer ie is it: (5x+10)/(x+2)•(2x)/(4x-10) or 5x+(10/x+2)•(2x/4x) -10

is makes a difference to the final answer

sorry, different problem, back
Jack1
  • Jack1
so: (5x+10)/(x+2) times (2x/(4x-10) yeah?
Jack1
  • Jack1
so when multiplying fractions, times numerator by numerator and denominator by denominator so top x top = (5x+10) times 2x = (5x +10)(2x)
Jack1
  • Jack1
botom times bottom = (x+2) times (4x-10) =(x +2)(4x-10)
Jack1
  • Jack1
so your long answer is : (5x +10)(2x) / (x +2)(4x-10) but you can further simplify this:
Jack1
  • Jack1
(5x +10)(2x) becomes 10x^2 +20x (x+2)(4x+10) becomes 4x^2 + 18x +20
Jack1
  • Jack1
now, you can take 2 out of top and bottom, so it becomes: 2(5x^2 +10x) / 2(2x^2 + 9x +10)
Jack1
  • Jack1
= (5x^2 +10x) /(2x^2 + 9x +10)
Jack1
  • Jack1
thats about it
