c=

32=-27x to the 2nd power +12x . Write the following equation in standard form and determine a b c?
Standerd form of a quadractic equation looks like this ax^2+bx+c=0 so to do that you would subtract 32 on both sides and you would get -27x^2+12x-32=0 however you would want to write it like this 27x^2-12x-32=0 the first coeffeiciant would be a = 27 the second coefficiant would be b= -12 and finally the constant c= -32 as a quadratic equation is ax^2+bx+c=0
Reply:Thats nearly correct unknown (above)





Unfortunately you made a mistake





When you changed all the signs you missed the sign on the 32, it should be positive.





a = 27


b = -12


c = 32





And nada J must be on drugs

32 = (-27X)^2 + 12X


32 = 729(x^2) + 12x


729(x^2) + 12x - 32 = 0





so i donno if u mean that


a = 729


b = 12


c = -32





i hope i was able to help


good luck!
