Question

how do I figure out how to factor a number this big...7n^2-3n-3322=0

Answer 1

quadratic formula is pretty straight forward

Answer 2

I'm trying the foil method

Answer 3

its better to just undo the quadratic, completing the square is the longhand method of the quadratic formula

Answer 4

I don't understand how to do that well

Answer 5

do you have to solve the equation or factor?

Answer 6

you cant factor

Answer 7

then its prolly best to just use the quadratic formula:

given: ax^2 + bx + c = 0

we can determine the roots as:

-b +- sqrt(b^2-4ac)
x = -----------------
2a

Answer 8

I am doing sequences and series

Answer 9

Ok, I will try that

Answer 10

would it look like this: x=3+-sqrt(9^2-4(7)(-3322) all over 2(7)?
