-0.75+2.25p-1.5p^2=1
We move all terms to the left:
-0.75+2.25p-1.5p^2-(1)=0
We add all the numbers together, and all the variables
-1.5p^2+2.25p-1.75=0
a = -1.5; b = 2.25; c = -1.75;
Δ = b2-4ac
Δ = 2.252-4·(-1.5)·(-1.75)
Δ = -5.4375
Delta is less than zero, so there is no solution for the equation
