I think the answer is the one I have marked but I am not sure?
yes, you are correct:)
I might be wrong here, but the last one should be the answer. Just going by the quadratic formula, the denominator should contain 2(a) and a=2 in this scenario, so the denominator would be 4
please medal if correct, thanks
could you explain why i am not sue how to get this?
Do you know the quadratic formula?
Okay, so the first step here is to add the 3 to the other side
Then you've got your polynomial. You'll need to plug the polynomial's numbers into the quadratic formula. Let me know what you get when you do that.Don't solve it just yet, only show what you did when you plugged them in
-6+-√-6^2-4(2)(3) / 2(2) ?
Very close. You just accidentally switched the sign for your 6^2
the b^2 is positive(unless b in the polynomial is negative)
So, now you've got the equation. What's next?
plug it in and solve? 2(2) would be 4 i guess like you said
It would be. That's the shortcut to your answer for this question in particular. Do you want to solve the rest just for your own sake or do you have it?
oh so it would be the last one? i was getting √3 - 3/2 for some reason
Did you maybe forget that the bottom was 2a? Only reason I remember that is because my Algebra 1 teacher a few years ago told us a story for the formula
I got the last one but I am not sure if its right either
Those are the ones I was never sure of haha. You might be able to use an online calculator and see if it actually passes through when you plug in each equation. I'm not positive on it
ok thank you :)
I figured it out just plug in x which is 4 and you get -1 so my equation works :)
