What would lead to a product of -3? (1,-3 or -1,3)
From the two end terms, what would add to -2? Since the first term has to be 1, the last term has to be -3 to = -2. Include the a and b terms.
I hope this helps.
Factor completely. Remember to look first for a common factor. Check by multiplying. If a polynomial is prime state this.
a^2-2ab-3b^2
