Question

What are the exact solutions of x^2 - 5x - 1 = 0?

x = 5± √29 / 2

x = -5 ± √29 / 2

x = 5 ± √21 / 2

x = -5 ± √21 / 2

Answer 2

apply Quadratic formula of roots

Answer 3

is that x = -b ± √b + 4ac / 2a ?

Answer 4

yeah

Answer 5

let me try

Answer 6

x = -(-5) ± √-5 + 4(1)(-1)
x = 5 ± √-9
Is this right so far?

Answer 8

no btw your formula is worng, now i see your formula carefully sorry for that

Answer 9

its ok and can you help me in about 15 or 20 minutes I have to go do something but i'll tag you hen im back

Answer 10

ok i can

Answer 11

-(-5) ± √ -5^2 - 4(1)(-1)/ 2(1)
5 ± √ 25 - (-4) / 2
5± √29 / 2
The answer would be 5 ± √29 / 2
