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

anonymous · Answer

No idea what a 'quadratic' is.

campbell_st · Answer

well its part of factoring... 

x^2 - 49 = (x -7)(x+7)

now you can put it all together

anonymous · Answer

I don't know how to put it together.

campbell_st · Answer

o well... maybe time to read some algebra

anonymous · Answer

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