300x-(2/5)x^2=0
Domain of the equation: 5)x^2!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
300x-(+2/5)x^2=0
We multiply all the terms by the denominator
300x*5)x^2-(+2=0
Wy multiply elements
1500x^2+2=0
a = 1500; b = 0; c = +2;
Δ = b2-4ac
Δ = 02-4·1500·2
Δ = -12000
Delta is less than zero, so there is no solution for the equation
