(P)=0.7P^2+12P+200
We move all terms to the left:
(P)-(0.7P^2+12P+200)=0
We get rid of parentheses
-0.7P^2+P-12P-200=0
We add all the numbers together, and all the variables
-0.7P^2-11P-200=0
a = -0.7; b = -11; c = -200;
Δ = b2-4ac
Δ = -112-4·(-0.7)·(-200)
Δ = -439
Delta is less than zero, so there is no solution for the equation
