I'm starting college this year, and I had to take a year off in order to collect some funds to help pay for it. I really don't remember how to factor something such as
$4x^2 + 4x - 35$
I know the answer to the problem to this question since it's a part of my readiness quiz study guide. But it was done in 1 step.
The answer to it is (2x-5) (2x+7). No other steps were done to factor the problem, it was just done in one step unlike the others such as $5x^3 - 20x$ which I understand how to do. And I understand how to do something like
$x^3 + 2x^2 - 9x - 18$. I can't really explain the terms used to solve something like this, but I get how to do it.
Another example of a problem I can't solve due to the rules of the formula is
That ends up just becoming $x^2 (8x^2 - 17x + 9)$ but where do I go from there? I have to factor the same way just like in the $4x^2 + 4x - 35$ problem.
Can someone please explain how this is supposed to be approached. I'd really appreciate it. Thank you.
