    Factoring Trinomials & GCF

    I'm stuck on these problems, can anyone help me? Thanks.

    1. 8x3 - 56x2 + 80x

    2.4v2 + 9v + 5

    3. 5c2 - 18c - 8

    4. 56b2 + 23b - 63

    5. 6a4 + 5a2 -25

    6. 3b3 - 9b2 - 54b

    Factoring GCF:

    7.3x8 y6 + 6x6 y5 +24xy

    Re: Factoring Trinomials & GCF

    1: factor out 8x and then you have a quadratic left you can solve using the quadratic formula (when you know the zeros of your polynomial you know the factors)
    2,3,4: directly apply quadratic formula
    5: Let x = a^2 and you have a quadratic through which you can directly solve with the quadratic formula.
    6: factor out 3b and then you have a quadratic left.
    7: factor 3xy

    For finding gcf it's mainly practice but in general if you have a polynomial, say x^n*y^m + x^t*y^v factor out x^a*y^b where a = min (n,t) and b = min(m,v)
