Question

4x2 - 7x = 2

Answer 1

Subtract both side by 2 then try to factor it.

If this cannot be factored, then use quadratic formula.

Do you know how to?

Answer 2

yes i do that then put it on here

Answer 3

do i do b^2-4ac

Answer 4

Well, you have 4x² - 7x = 2

You need to do this:

4x² - 7x - 2 = 2 - 2
4x² - 7x - 2 = 0

Answer 5

if it cannot be factored, then you can use this formula.

Answer 6

\[\Large x = \frac{-b \pm \sqrt{ b^2 - 4ac }}{2a}\]

Answer 7

it doesnt factor in 7

Answer 8

Ok, then use formula, just like I told you to.

Answer 9

ok i got -1/4,2

Answer 10

That's correct. Good work.
