Use the quadratic formula to solve the equation.
-x^2+5x=11
a.5/2 +- sqrt13/2
b.-5/2 +- sqrt13/2
c.2/5 +- sqrt13/2
d.-2/5 +- sqrt13/2
-x^2+5x=11
a.5/2 +- sqrt13/2
b.-5/2 +- sqrt13/2
c.2/5 +- sqrt13/2
d.-2/5 +- sqrt13/2

first make the equation more presentable
....
x^2 - 5x + 11 = 0
x = (5 ± √-19)/2
none of the answers match this, so there has to be a typo.
since all answers contain √13
your equation could have been
x^2 - 5x + 3 = 0
that would give you x = (5 ± √13)/2, which matches a)
check your typing.

then, as I said before,
x = (5 ± √-19)/2
none of the choices match, that's all there is to say.
