Factor the polynomial completely. 6y^3-8y^2-30y

Question

pfenn1 · Answer

$$6y^3-8y^2-30y$$The first thing I would do is factor out 2y.  What would you be left with?

anonymous · Answer

6y^(3)-8y^(2)-30y

Factor out the GCF of 2y from each term in the polynomial.
2y(3y^(2))+2y(-4y)+2y(-15)

Factor out the GCF of 2y from 6y^(3)-8y^(2)-30y.
2y(3y^(2)-4y-15)

Find the factors such that the product of the factors is the trinomial 3y^(2)-4y-15.  This can be done by trial and error and checked using the FOIL method of simplifying polynomials.
2y(3y+5)(y-3)
