Factor 2x^3-98a^2x+28x^2+98x

QUESTION:

Would it make sense to divide EVERY coefficient in the polynomial by the leading coefficient of 2 to reduce the BIG numbers?

Is there an easier method?

Well, I wouldn't call it "dividing".

You can*factor out*a . . . it's a**factoring**problem, remember?

Thank you for your tips.

To OReilly:

The variable a belongs to the second term.

If it is a typo, I would not know.

So, what is the final answer? - January 20th 2007, 09:52 AMSoroban
Hello again, symmetry!

If the problem is correctly stated, it's a sneaky one . . .

Soroban,

I guess the answer to OReilly's question is: Yes, the letter a is part of the question.

Thanks!
