Example: x^2+3x-5=0
Answer : -3- sqrt 29/2, -3+sqrt 29/2 (exact solutions)

Can someone help me put this in three decimal forum
Answered by DrBob222
I don't know if that is -3-(sqrt 29)/2 or
-3-sqrt (29/2). If the latter, then
-3-sqrt(14.5) = -3-3.80789 =-6.80789 = -6.808 to three decimal places.
Check my work.

I think you mean
[-3- sqrt 29]/2, [-3+sqrt 29]/2
That corresponds to -4.193.. and 1.193

-4.193.. and 1.193

But how are you coming up with these numbers? This is the answer, I am clueless to how your finding it... what do I need to do to figure this problem out?
Answered by ~christina~
well it is simple as stated.

for the second one it is:
[-3+sqrt 29]/2

so
1. sqrt 29
2. -3 + (sqrt 29)
3. (divide the number found in 2. by the number 2 which would be=>
[-3+sqrt 29]/2

I used a hand calculator and the given formula, that's how.

You said you wanted it in decimal form, but I would expect any teacher to prefer the exact form containing sqrt(29).

When approximating to three decimal places (I've just since realized you HAVE to have a calculator to do this) what buttons on the calculator are you pushing to get the answer?
