=0.0089P^2+1.1149P+78.4491
We move all terms to the left:
-(0.0089P^2+1.1149P+78.4491)=0
We get rid of parentheses
-0.0089P^2-1.1149P-78.4491=0
a = -0.0089; b = -1.1149; c = -78.4491;
Δ = b2-4ac
Δ = -1.11492-4·(-0.0089)·(-78.4491)
Δ = -1.54978595
Delta is less than zero, so there is no solution for the equation
