Question

How do you factor and solve `2x² -452x-68,640=0`?

Answer 1

Given a choice I'd probably solve first, then factor, but:

`2x^2-452x-68,640=2(x^2-226x-34,320)`

By considering all possibilities for factoring `x^2-226x-34320)`
I eventually got to `(x-330)(x+104)` which works. So the solutions to the equation are `330` , `-104`.
