0=x^2+3.8x+5.8
We move all terms to the left:
0-(x^2+3.8x+5.8)=0
We add all the numbers together, and all the variables
-(x^2+3.8x+5.8)=0
We get rid of parentheses
-x^2-3.8x-5.8=0
We add all the numbers together, and all the variables
-1x^2-3.8x-5.8=0
a = -1; b = -3.8; c = -5.8;
Δ = b2-4ac
Δ = -3.82-4·(-1)·(-5.8)
Δ = -8.76
Delta is less than zero, so there is no solution for the equation
