Question

What are the exact solutions of x2 − 3x − 7 = 0?

Answer 1

u know quadratic formula ?

Answer 2

uh mayybbbee \[\frac{ -b+-\sqrt{b ^{2}}-4ac }{ 2a }\]

Answer 3

yes:)
can u find a,b,c here ?

Answer 4

and to be precise :
the two roots of x are:
\(\huge{x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

Answer 5

a=1 b=-3 c=-7?

Answer 6

yes, now just put them in formula.

Answer 7

ok hold on :)

Answer 8

ok it would be \[x=\frac{ 3+-\sqrt{37} }{ 2}\]

Answer 9

?

Answer 10
