Factor 6x4 - 5x2 + 12x2 – 10 by grouping. What is the resulting expression? O (6x + 5)(x2 - 2) O (6x - 5)(x2 + 2) (6x2 + 5)(x - 2) (6x2 - 5)(x2 + 2) ​

()()

Step-by-step explanation:

Always arrange in descending powers first.  In this case that is already done.

Try grouping the first two terms and the last two terms first

  Factor out the GCF of both groups

    Note that is a factor in each group. That's    

                                           good

Now treat as a GCF and you get

()()

Since    and    are both prime, we are finished.  

You can check to see if you are correct by FOILing the answer you got.  OK?
