Question

Factor the GCF first and then factor the resulting binomial: 2x3 - 98x


2x(x + 49)(x - 49)


2x(x + 7)(x - 7)


2x(x + 14)(x - 14)


prime

Answer 1

2x(x^2 - 49) is a good start... see if you can finish it.... (hint the quadratic is the difference of 2 squares)

Answer 2

No idea what a 'quadratic' is.

Answer 3

well its part of factoring...

x^2 - 49 = (x -7)(x+7)

now you can put it all together

Answer 4

I don't know how to put it together.

Answer 5

o well... maybe time to read some algebra

Answer 6

That would be what I'm doing and How I ended up here.... to get help.
