anonymous · Answer

Try factoring the stuff in the numerator.  Also factor the denominator.  Look for anything you can cancel to simplify.

I got an answer but it looks completely wrong, and I have no where to check it.

one thing to know... is dividing  a fraction by a fraction, invert and multiply. 

$$\frac{4t^2 - 1}{15t + 1} \times \frac{3t^2 + 5t + 2}{4t^2 -4t + 1}$$

now you have it in this form... 

factorise and the common factors that can be cancelled will become obvious

oops missing a zero in the denominator of the 1st fraction

whats your answer

(2t+2)(x+3)(x+2)/5(3t+2)(2t-1). I know it can't be right, it looks totally wrong.
