(R)=0.0709R^2+1.370R+2.0948
We move all terms to the left:
(R)-(0.0709R^2+1.370R+2.0948)=0
We get rid of parentheses
-0.0709R^2+R-1.370R-2.0948=0
We add all the numbers together, and all the variables
-0.0709R^2-0.37R-2.0948=0
a = -0.0709; b = -0.37; c = -2.0948;
Δ = b2-4ac
Δ = -0.372-4·(-0.0709)·(-2.0948)
Δ = -0.45718528
Delta is less than zero, so there is no solution for the equation
