-1(F)=F+4/2F+3
We move all terms to the left:
-1(F)-(F+4/2F+3)=0
Domain of the equation: 2F+3)!=0We get rid of parentheses
F∈R
-1F-F-4/2F-3=0
We multiply all the terms by the denominator
-1F*2F-F*2F-3*2F-4=0
Wy multiply elements
-2F^2-2F^2-6F-4=0
We add all the numbers together, and all the variables
-4F^2-6F-4=0
a = -4; b = -6; c = -4;
Δ = b2-4ac
Δ = -62-4·(-4)·(-4)
Δ = -28
Delta is less than zero, so there is no solution for the equation
