(1.25+x)(0.75+x)/2=0.0000178
We move all terms to the left:
(1.25+x)(0.75+x)/2-(0.0000178)=0
We add all the numbers together, and all the variables
(x+1.25)(x+0.75)/2-(1.78E-5)=0
We add all the numbers together, and all the variables
(x+1.25)(x+0.75)/2+0.1614583453429=0
We multiply parentheses ..
(+x^2+0.75x+1.25x+0.9375)/2+0.1614583453429=0
We multiply all the terms by the denominator
(+x^2+0.75x+1.25x+0.9375)+(0.1614583453429)*2=0
We add all the numbers together, and all the variables
(+x^2+0.75x+1.25x+0.9375)+0.3229166906858=0
We get rid of parentheses
x^2+0.75x+1.25x+0.9375+0.3229166906858=0
We add all the numbers together, and all the variables
x^2+2x+1.2604166906858=0
a = 1; b = 2; c = +1.2604166906858;
Δ = b2-4ac
Δ = 22-4·1·1.2604166906858
Δ = -1.0416667627432
Delta is less than zero, so there is no solution for the equation
