0.2016=0.277-0.0056x+0.0000478x^2
We move all terms to the left:
0.2016-(0.277-0.0056x+0.0000478x^2)=0
We get rid of parentheses
-0.0000478x^2+0.0056x-0.277+0.2016=0
We add all the numbers together, and all the variables
-5x^2+0.0056x-0.0754-4.78E=0
We add all the numbers together, and all the variables
-5x^2+0.0056x-13.06878714=0
a = -5; b = 0.0056; c = -13.06878714;
Δ = b2-4ac
Δ = 0.00562-4·(-5)·(-13.06878714)
Δ = -261.37571144
Delta is less than zero, so there is no solution for the equation
