In the last video we factor this polynomial in order to find the real roots we factored it by grouping which is essentially doing the distributive property in Reverse twice and I mentioned that there's two ways you could do it you could actually from the getgo add these two middle degree terms and then think about it and then think about it from there and so what I thought I would do is just Example 6 Find a cubic polynomial with the sum of its zeroes, sum of the products of its zeroes taken two at a time, and product of its zeroes as 2, – 7 and –14, respectively Sol Let the cubic polynomial be ax 3 bx 2 cx d
