If ax²+bx+c=0 and a≠0, x1 and x2 are a) real and different if the discriminant D is:
b) real and equal if the discriminant D is:​

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

i don't think there is enough
