(x^2-12x+36)/7x^2+14=0
Domain of the equation: 7x^2!=0We multiply all the terms by the denominator
x^2!=0/7
x^2!=√0
x!=0
x∈R
(x^2-12x+36)+14*7x^2=0
Wy multiply elements
98x^2+(x^2-12x+36)=0
We get rid of parentheses
98x^2+x^2-12x+36=0
We add all the numbers together, and all the variables
99x^2-12x+36=0
a = 99; b = -12; c = +36;
Δ = b2-4ac
Δ = -122-4·99·36
Δ = -14112
Delta is less than zero, so there is no solution for the equation
