Question

solve for x using the quadratic formula
x2+5x-1=0

Answer 1

now this one you need the formula for

Answer 2

use
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] with
\[a=1,b=5,c=-1\] you get
\[x=\frac{-5\pm\sqrt{5^2-4\times 1\times -1}}{2\times1}\]
\[\frac{-5\pm\sqrt{25+4}}{2}\]
\[\frac{-5\pm\sqrt{29}}{2}\]

Answer 3

after this

Answer 4

He gave you the answers. There are two. Compute -5+root(29)/2 and -5-root(29)/2

Answer 5

more than this there is nothing
