To start this type of problem find the product of the coefficient (here -3) of and the constant term (here 8). Consider the positive value of the product (). Try to express the coefficient of 's' i.e. -10 as a sum of two numbers whose product is, here, 24. Then you would be able to find some expressions common and will be able to factorize.

You can put this solution on YOUR website! you will have to learn the "binomial" factoring technique... look at the website's Lessons. there must be plenty of help there:
anyway, the answer is:
Multiply these brackets out and you will get the polynomial in the question.
