in another question
OpenStudy (anonymous):
-2x^2+5x-3=0
OpenStudy (amorfide):
since you said it is a complex number, my assumption would be you need the values of x?
sub the values into the quadratic equations
|dw:1350231416112:dw|
OpenStudy (anonymous):
yes

substitute into the equation, let us know how far you get
OpenStudy (anonymous):
i don't how to do it
OpenStudy (amorfide):
okay you have
-2x²+5x-3=0
here you have a coefficient of x² a coefficient of x and a constant
these are your a, b, and c
coefficient of x²=a
coefficient of x=b
constant=c
so tell me the values of a b and c
OpenStudy (anonymous):
a = -2 b=5x c=-3
OpenStudy (amorfide):
no b=5 not 5x

okay so now we have
a=-2
b=5
c=-3
now substitute into the equation i give you
