3(x2-2)+18=0
We add all the numbers together, and all the variables
3(+x^2-2)+18=0
We multiply parentheses
3x^2-6+18=0
We add all the numbers together, and all the variables
3x^2+12=0
a = 3; b = 0; c = +12;
Δ = b2-4ac
Δ = 02-4·3·12
Δ = -144
Delta is less than zero, so there is no solution for the equation
