Question

Hello I need help with a quadratic formula

Answer 1

It asks what the smaller root is and what the larger root is! And I am not sure what it means by that.

Answer 2

Start by simplifying under the radical. Once you do, the two solutions come from the ± sign. Add to get one and subtract for the other

Answer 3

yes but....

Answer 4

have you approximated both values yet?

Answer 5

\[x=\frac{-(-5) + \sqrt{(-5)^2-4(-2)(-2)}}{2(-2)} \approx ? \\ x=\frac{-(-5)- \sqrt{(-5)^2-4(-2)(-2)}}{2(-2)} \approx ?\]

Answer 6

wait hold on lemme do it ok

Answer 7

actually these both come out very nicely
no need for approximations

Answer 8

I dont understand what it asks by the smaller and larger root

Answer 9

well can you tell me what you got from the above computations ?
