-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

OpenStudy (amorfide):

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

OpenStudy (amorfide):

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

OpenStudy (anonymous):
