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
7.3x8 y6 + 6x6 y5 +24xy
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 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 factor out where and
