Is this correct? \[\frac{ 5x^2 + 9x - 2 }{ x^2 + 12x + 20 } \times \frac{ x^2 + 17x + 70 }{ 15x - 3 }\]

Yes

Try factorising each part of the expression, you'll find some factors on the top and bottom of the fraction that cancel out.

Ok I did but I think im doing something wrong

What did you get when you factorised it all?
anonymous
  • anonymous
\[5x2+9x-2 \] \[(x+2) (x+10)\]
anonymous
  • anonymous
\[(x+10) ( x+7)\] \[3(5x)\]

The first one can be factorised, so you get \[5x^2 + 9x - 2 = (5x-1)(x+2)\] and you forgot a term on the denominator of the 2nd bit, you should get \[3(5x-1)\] instead of \[3(5x)\] When you change that, you should get a bunch of cancellation :)
